一：驗法

採前確現場合法、目類非保。

FUNDAMENTAL RULE:
Never collect without proper authorization. Never collect from
protected areas without explicit permits. Never collect protected
species. The scientific value of a specimen is zero if it was
collected illegally — it cannot be published, deposited in a
museum, or used in formal research.

Legal Checklist:
+--------------------+------------------------------------------+
| Requirement        | Verify                                   |
+--------------------+------------------------------------------+
| Land access        | Written permission from landowner, or    |
|                    | site is publicly accessible for          |
|                    | collecting (many parks prohibit it)      |
+--------------------+------------------------------------------+
| Collection permit  | Required for most public lands, nature   |
|                    | reserves, national parks. Apply through  |
|                    | the managing agency. Specify taxa,       |
|                    | methods, dates, and quantities.          |
+--------------------+------------------------------------------+
| Protected species  | Check national and regional red lists,   |
|                    | CITES appendices, and local endangered   |
|                    | species legislation. Some butterflies,   |
|                    | beetles, and dragonflies are protected.  |
+--------------------+------------------------------------------+
| Export/import      | Moving specimens across international    |
|                    | borders requires phytosanitary           |
|                    | certificates and may require CITES       |
|                    | permits depending on the taxon.          |
+--------------------+------------------------------------------+
| Institutional      | If collecting for an institution, follow |
| protocols          | their collection policy and ethics       |
|                    | review requirements.                     |
+--------------------+------------------------------------------+

Minimizing Collection Impact:
- Collect only the minimum number of specimens needed
- Avoid collecting from small or isolated populations
- Do not collect gravid (egg-bearing) females if population is small
- Record the abundance at the site — if the species appears rare, photograph instead
- Prefer common and abundant species for teaching collections

得： 諸執照已得、保種列已察、採者明場中何可採何不可。

敗： 不得證→勿採。原位攝影，用公民科學平臺識。若誤採保種→速諮野保署。勿棄標——誤採宜報非藏。

二：擇法

配目類、境、研究之法。各法採蟲群之異部。

Collection Methods:
+--------------------+------------------------------------------+
| Method             | Best For                                 |
+--------------------+------------------------------------------+
| Sweep net          | Flying and vegetation-dwelling insects    |
|                    | in grasslands, meadows, and low shrubs.  |
|                    | Technique: sweep in a figure-8 pattern   |
|                    | through vegetation; empty net into a     |
|                    | killing jar or collecting bag after      |
|                    | every 10-20 sweeps.                      |
+--------------------+------------------------------------------+
| Beating tray       | Arboreal insects on trees and shrubs.    |
|                    | Hold a white sheet or tray under a       |
|                    | branch; strike the branch sharply 3-5    |
|                    | times; collect dislodged insects with    |
|                    | an aspirator or forceps.                 |
+--------------------+------------------------------------------+
| Pitfall trap       | Ground-dwelling insects (beetles,        |
|                    | ants, crickets). Bury a cup flush with   |
|                    | the soil surface. Add a rain cover.      |
|                    | Check every 24-48 hours. Use propylene   |
|                    | glycol as preservative (non-toxic to     |
|                    | mammals; do not use ethylene glycol).    |
+--------------------+------------------------------------------+
| Light trap         | Nocturnal flying insects (moths, many    |
|                    | beetles, lacewings). Use a white sheet   |
|                    | illuminated by a mercury vapor or UV     |
|                    | light. Operate from dusk to midnight     |
|                    | or dawn. Most effective on warm, humid,  |
|                    | moonless nights.                         |
+--------------------+------------------------------------------+
| Malaise trap       | Flying insects, especially Hymenoptera   |
|                    | and Diptera. A tent-like mesh barrier    |
|                    | that intercepts insects in flight;       |
|                    | they walk upward into a collecting head  |
|                    | containing preservative. Runs            |
|                    | continuously; check weekly.              |
+--------------------+------------------------------------------+
| Aspirator (pooter) | Small, delicate insects that cannot be   |
|                    | handled with forceps. Suck the insect    |
|                    | into a vial through a tube (a mesh      |
|                    | filter prevents inhalation). Use only    |
|                    | mouth-operated aspirators with a filter. |
+--------------------+------------------------------------------+
| Pan trap           | Pollinators and small flying insects.    |
|                    | Colored bowls (yellow, white, blue)      |
|                    | filled with soapy water. Place at        |
|                    | vegetation height. The soap breaks       |
|                    | surface tension; insects fall in and     |
|                    | drown. Check every 24-48 hours.          |
+--------------------+------------------------------------------+
| Hand collection    | Large, slow, or sessile insects.         |
|                    | Pick directly with forceps or fingers.   |
|                    | Useful for bark-dwelling beetles,        |
|                    | caterpillars on host plants, aquatic     |
|                    | larvae under rocks.                      |
+--------------------+------------------------------------------+

得： 依目類與境擇一或多法，具備齊而待入場。

敗： 預法無獲（如雨中掃網）→換法。燈誘須特氣候——暖濕靜無月夜最佳。氣候劣→改期勿低效行陷。

三：速殺

速且人道殺所採。久痛損標（肢斷、鱗失）且不倫。

Dispatch Methods:
+--------------------+------------------------------------------+
| Method             | Procedure and Notes                      |
+--------------------+------------------------------------------+
| Ethyl acetate      | Place a wad of absorbent material        |
| killing jar        | (plaster of Paris or tissue) in the      |
|                    | bottom of a wide-mouth jar. Saturate     |
|                    | with ethyl acetate. Place insects in     |
|                    | the jar; death occurs within 1-5        |
|                    | minutes for most species.                |
|                    | Caution: ethyl acetate is flammable and  |
|                    | an irritant. Use in well-ventilated     |
|                    | areas. Do not inhale.                    |
+--------------------+------------------------------------------+
| Freezing           | Place live insects in a container in a   |
|                    | freezer at -20C for 24 hours. Suitable   |
|                    | for specimens brought back alive.        |
|                    | Produces well-relaxed specimens ideal    |
|                    | for pinning.                             |
+--------------------+------------------------------------------+
| Ethanol drowning   | Immerse directly in 70-95% ethanol.      |
|                    | Used for soft-bodied insects that will   |
|                    | be wet-preserved (larvae, aphids, small  |
|                    | Diptera). Not suitable for Lepidoptera   |
|                    | (destroys scales) or specimens intended  |
|                    | for dry pinning.                         |
+--------------------+------------------------------------------+

NEVER use:
- Cyanide jars (potassium cyanide) — extremely toxic to humans;
  obsolete in modern entomology
- Crushing or squeezing — destroys morphological features
- Prolonged suffocation — slow and damages specimens from struggling

得： 分鐘內速殺，形損微。鱗翅別置防鱗失。

敗： 無乙酸乙酯→凍最佳。場外無→單管或信封（鱗翅用硫酸紙翅折）歸而凍。勿留活蟲於封器無殺劑——自損。

四：針標（乾存）

每標依目針正位。位正為診特徵取與久結構之要。

Pin Placement by Order:
+--------------------+------------------------------------------+
| Order              | Pin Position                             |
+--------------------+------------------------------------------+
| Coleoptera         | Through the RIGHT ELYTRON (front wing    |
| (beetles)          | cover), approximately 1/3 from the       |
|                    | anterior edge, so the pin emerges        |
|                    | between the middle and hind legs.        |
+--------------------+------------------------------------------+
| Lepidoptera        | Through the CENTER OF THE THORAX         |
| (butterflies/moths)| (mesothorax), between the wing bases.    |
|                    | Wings must be spread on a spreading      |
|                    | board before the specimen dries.         |
+--------------------+------------------------------------------+
| Hymenoptera        | Through the RIGHT SIDE OF THE THORAX     |
| (bees/wasps/ants)  | (mesothorax), between the wing bases.    |
+--------------------+------------------------------------------+
| Diptera            | Through the RIGHT SIDE OF THE THORAX     |
| (flies)            | (mesothorax), between the wing bases.    |
+--------------------+------------------------------------------+
| Hemiptera          | Through the RIGHT SIDE OF THE            |
| (true bugs)        | SCUTELLUM (triangular plate between      |
|                    | wing bases), slightly to the right of    |
|                    | center.                                  |
+--------------------+------------------------------------------+
| Orthoptera         | Through the RIGHT SIDE OF THE            |
| (grasshoppers)     | PRONOTUM (just behind the head), to      |
|                    | the right of the midline.                |
+--------------------+------------------------------------------+
| Odonata            | Through the CENTER OF THE THORAX.        |
| (dragonflies)      | Wings must be spread. Alternatively,     |
|                    | store in glassine envelopes.             |
+--------------------+------------------------------------------+
| All other orders   | Through the RIGHT SIDE OF THE THORAX     |
|                    | unless order-specific guidance is        |
|                    | available.                               |
+--------------------+------------------------------------------+

Pin Selection:
- Standard entomological pins: stainless steel, sizes 0-7
- Size 3 (0.50mm) is the most commonly used general-purpose size
- Size 1-2 for small beetles and flies; size 4-5 for large beetles
- Specimens under 5mm: mount on a paper point (triangular card
  glued to a standard pin) rather than pinning directly

Pin Height:
- The specimen should sit approximately 2/3 up the pin (leaving
  room below for 2 labels and above for handling)
- Use a pinning block (stepped block with 3 heights) to ensure
  consistent specimen and label heights across the collection

Spreading Wings (Lepidoptera, Odonata):
1. Pin the specimen through the thorax
2. Place on the spreading board with the body in the groove
3. Use paper strips to hold wings in position
4. Adjust wings so the hind margin of the forewing is perpendicular
   to the body axis
5. Leave on the board for 3-7 days until completely dry
6. Remove paper strips carefully

得： 每標依目針正位、針高正、鱗翅蜻蜓翅展。標全乾方動。

敗： 標過乾脆（肢斷翅裂）→須先鬆。入鬆弛室（封器附濕砂或紙巾加數滴苯酚防霉）24-48 時至肢柔。位誤→趁新重針勝留誤。

五：乙醇存（濕存）

軟體乾則縮或變者須液存。

Wet Preservation Protocol:
+--------------------+------------------------------------------+
| Category           | Procedure                                |
+--------------------+------------------------------------------+
| Preservative       | 70-80% ethanol for morphological study.  |
|                    | 95-100% ethanol for DNA-grade            |
|                    | preservation (change ethanol after 24    |
|                    | hours to remove dilution from body       |
|                    | fluids).                                 |
+--------------------+------------------------------------------+
| Suitable specimens | Larvae (caterpillars, grubs, maggots),   |
|                    | soft-bodied adults (aphids, termites,    |
|                    | some small Diptera), aquatic insects,    |
|                    | immature stages (nymphs, pupae)          |
+--------------------+------------------------------------------+
| Containers         | Glass vials with screw caps or           |
|                    | polyethylene snap-cap vials. Avoid       |
|                    | rubber stoppers (ethanol dissolves       |
|                    | them). Label goes INSIDE the vial.       |
+--------------------+------------------------------------------+
| Fluid ratio        | At least 3 parts preservative to 1 part  |
|                    | specimen volume. Too little fluid        |
|                    | results in poor preservation.            |
+--------------------+------------------------------------------+
| Long-term storage  | Check fluid levels every 6-12 months.    |
|                    | Ethanol evaporates even through sealed   |
|                    | caps. Top up as needed. Store in a cool, |
|                    | dark location.                           |
+--------------------+------------------------------------------+

Do NOT use:
- Formaldehyde/formalin for routine insect preservation (destroys DNA,
  poses health risks, requires special disposal). Some historical
  collections used it; modern practice strongly discourages it.
- Isopropanol as a substitute — it causes excessive hardening and
  color loss compared to ethanol.

得： 軟體存於 70-80% 乙醇（DNA 工 95%+），液足於有標之管。

敗： 場外無乙醇→暫以高度烈酒（伏特加、Everclear）存。速轉實驗級乙醇。久存於弱液而腐→形或可識，分子不可。

六：標每件

每標須有籤供科用最低數據。無籤標無科值。

Labeling Standards:

LABEL 1 (Locality label — placed closest to the specimen on the pin):
  Line 1: Country, State/Province
  Line 2: Specific locality (e.g., "3 km NE of Oakville, Elm Creek trail")
  Line 3: Latitude/Longitude (decimal degrees preferred)
  Line 4: Elevation (meters above sea level)
  Line 5: Date (e.g., 15.vi.2026 or 15-Jun-2026)
  Line 6: Collector name (e.g., "leg. P. Thoss")

LABEL 2 (Habitat/method label — below the locality label):
  Line 1: Habitat (e.g., "deciduous forest, oak canopy")
  Line 2: Collection method (e.g., "sweep net" or "light trap")
  Line 3: Additional ecological data if relevant

LABEL 3 (Determination label — lowest on the pin, added when identified):
  Line 1: Order Family
  Line 2: Genus species Author, Year
  Line 3: "det. [identifier name], [year]"

Label Format Rules:
- Use archival-quality paper (acid-free, resistant to fumigant chemicals)
- Print labels using a laser printer (inkjet fades; handwriting smudges)
- Labels should be small (approximately 13mm x 8mm) — do not obscure
  the specimen
- For wet specimens, the label goes INSIDE the vial on acid-free paper
  written in pencil or printed with a laser printer (ink dissolves in
  ethanol; pencil graphite does not)
- Pin labels below the specimen using the pinning block for consistent
  heights

得： 每標至少有地籤含國、地、座標、日、採者。濕標同數據於管內鉛筆或激光印之籤。

敗： 場中未記 GPS→按圖估。日不確→最佳估加問號。近數據之標遠勝無籤。勿移籤於他標。

七：存護集

妥存護標防傷、蟲、境敗。

Dry Collection Storage:
+--------------------+------------------------------------------+
| Component          | Standard                                 |
+--------------------+------------------------------------------+
| Unit trays         | Cardboard or plastic trays with foam     |
|                    | bottoms (plastazote preferred — pinnable |
|                    | and chemically inert). Specimens pinned  |
|                    | into the foam in organized rows.         |
+--------------------+------------------------------------------+
| Drawers            | Tight-fitting drawers that exclude dust  |
|                    | and pests. Glass-topped drawers allow    |
|                    | viewing without opening.                 |
+--------------------+------------------------------------------+
| Cabinets           | Steel cabinets with tight seals.         |
|                    | Compressed-air gaskets are ideal.        |
+--------------------+------------------------------------------+
| Pest management    | Place pest strips (dichlorvos/DDVP) or   |
|                    | naphthalene/paradichlorobenzene crystals  |
|                    | in each drawer. Check and replace every  |
|                    | 6 months. Museum beetle (Anthrenus) and  |
|                    | book lice (Psocoptera) are the primary   |
|                    | pests — a single infestation can destroy |
|                    | an entire drawer.                        |
+--------------------+------------------------------------------+
| Climate control    | Target: 40-50% relative humidity,        |
|                    | 18-22C temperature. Fluctuations cause   |
|                    | expansion/contraction damage. Avoid      |
|                    | direct sunlight (fades color).           |
+--------------------+------------------------------------------+

Wet Collection Storage:
- Store vials upright in racks or jars
- Check fluid levels every 6-12 months; top up with fresh ethanol
- Store in a cool, dark, well-ventilated area (ethanol fumes)
- Keep away from ignition sources (ethanol is flammable)
- For long-term storage, use screw-cap glass vials; snap-cap
  plastic vials allow more evaporation

得： 乾標存於封抽加蟲劑。濕標豎存液足。存處溫濕穩。

敗： 無館級存→存於氣密塑器（工具箱、Tupperware）加泡沫與蟲劑。此足於私集與短存。久存有科值之標→存於館或大學集。

八：整與入庫

以系統整與數據管維集如活科資。

Curation Tasks:
+--------------------+------------------------------------------+
| Task               | Frequency                                |
+--------------------+------------------------------------------+
| Pest inspection    | Every 3-6 months. Look for frass (fine   |
|                    | powder under specimens), cast skins,     |
|                    | or live pests in drawers.                |
+--------------------+------------------------------------------+
| Fumigant refresh   | Every 6 months. Replace pest strips or   |
|                    | crystals. Ensure drawers seal tightly.   |

Database Entry (minimum fields):
- Catalog number (unique identifier for each specimen)
- Taxon (order, family, genus, species)
- Locality (country, state, specific location, coordinates)
- Date of collection
- Collector
- Collection method
- Determiner and determination date
- Storage location (cabinet, drawer, row, position)
- Preservation type (pinned, ethanol, slide-mounted, point-mounted)

Database Standards:
- Use Darwin Core format for interoperability with global databases
  (GBIF, iDigBio)
- Record coordinates in decimal degrees (WGS84 datum)
- Use ISO 8601 date format (YYYY-MM-DD) in databases
- Assign a unique catalog number to every specimen, even if unidentified

得： 諸標入庫有唯一識、類、地、日、採者、存處。集於常察與維期表。

敗： 全庫不可行→至少手目或表，編號對標。編號鏈標與數據——無之則籤失時兩斷。簡單編號列亦勝於無目。

驗

• 採前法求已驗、證已得；法合目類與境
• 速人道殺；乾標依目針正位
• 鱗翅蜻蜓乾前翅展；軟體存於 70-80% 乙醇
• 每標有地籤含日、地、座標、採者
• 濕標籤鉛筆或激光印且於管內
• 存含蟲劑與穩境；諸標入庫或簿有唯一識

忌

• 無證採：非法標不可發、不入館、不越境。先得權。
• 過採：損群無科益。每形種每場 5-10 個足矣。
• 混場針誤：每採事獨器獨暫籤（混則地數據失）；甲蟲針胸心非右翅蓋→隱診。
• DNA 乙醇低：分子須 95%+ 且 24 時後換；70% 蝕 DNA。
• 忘濕標內籤：外籤可脫；必置鉛筆或激光印籤於管內。
• 忽蟲管：皮蠹數週毀全抽；常察與蟲劑換為必。
