步驟

步驟一：錄位置、日期、天氣

於近昆蟲前捕其背景。許多種繫於特定生境且有季節活動之性，故此元數據與照片同要。

Sighting Record — Context:
+--------------------+------------------------------------------+
| Field              | Record                                   |
+--------------------+------------------------------------------+
| Date               | Full date and time (e.g., 2026-06-15,    |
|                    | 14:30 local time)                        |
+--------------------+------------------------------------------+
| Location           | GPS coordinates if available; otherwise   |
|                    | describe precisely (e.g., "south bank of |
|                    | Elm Creek, 200m east of footbridge")     |
+--------------------+------------------------------------------+
| Elevation          | Meters above sea level if available       |
+--------------------+------------------------------------------+
| Weather            | Temperature (estimate is fine), cloud     |
|                    | cover, wind, recent rain                 |
+--------------------+------------------------------------------+
| Season phase       | Early spring, late spring, summer, early  |
|                    | autumn, late autumn, winter              |
+--------------------+------------------------------------------+

預期： 背景記錄齊備，含日期、時間、精確位置（理想為 GPS 座標）、觀察時之天氣條件。

失敗時： GPS 不可用時，以地標（步道交口、建築、水景）相對描述位置，詳至可重尋之度。天氣數據不確時，估溫度範圍並註「陰」或「晴」，勿空之。

步驟二：錄生境與微生境

錄昆蟲於景觀中之何處及其所用之直接底質或結構。

Habitat Recording:
+--------------------+------------------------------------------+
| Factor             | Record                                   |
+--------------------+------------------------------------------+
| Broad habitat      | Deciduous forest, grassland, wetland,    |
|                    | urban garden, riparian corridor, desert   |
+--------------------+------------------------------------------+
| Microhabitat       | Underside of leaf, bark crevice, flower   |
|                    | head, soil surface, under rock, on water  |
|                    | surface, in flight                       |
+--------------------+------------------------------------------+
| Substrate          | Specific plant species if known, dead     |
|                    | wood, dung, carrion, bare soil, rock     |
+--------------------+------------------------------------------+
| Plant association  | What plant is the insect on or near?     |
|                    | (host plant relationships are diagnostic) |
+--------------------+------------------------------------------+
| Light conditions   | Full sun, partial shade, deep shade       |
+--------------------+------------------------------------------+
| Moisture           | Dry, damp, wet, submerged margin          |
+--------------------+------------------------------------------+

預期： 生境之描述，置昆蟲於生態背景之中，含廣景觀與發現之直接微生境。

失敗時： 微生境難以刻畫（如飛行中之昆蟲）時，錄其所飛近者或所停者。錄「飛於草地之上 1 公尺」而勿空欄。

步驟三：以診斷質量拍照

良照片為目擊記錄之最要。公民科學之鑑定幾全賴圖像質量。

Photography Protocol:

Shots to take (in priority order):
1. DORSAL (top-down) — shows wing pattern, body shape, coloration
2. LATERAL (side view) — shows leg structure, body profile, antennae
3. FRONTAL (head-on) — shows eyes, mouthparts, antennae base
4. VENTRAL (underside) — if accessible, shows leg joints, abdominal pattern
5. SCALE REFERENCE — place a coin, ruler, or finger near the insect
   for size comparison (do not touch the insect)

Tips for quality macro photographs:
- Get as close as your camera allows while maintaining focus
- Use natural light; avoid flash if possible (causes glare and flattens detail)
- Shoot against a neutral background when feasible (leaf, paper, hand)
- Hold the camera parallel to the insect's body plane for maximum sharpness
- Take multiple shots at each angle — at least 3 per view
- If the insect is moving, use burst mode or continuous shooting
- Photograph the insect in situ first, then closer shots if it remains
- Include at least one photo showing the insect in its habitat context
- If wings are open, photograph quickly — the pattern may change when
  wings close (especially butterflies and dragonflies)

預期： 至少三張可用照片：一張背面、一張側面、一張帶比例參考。理想為五張以上，涵蓋多角度。

失敗時： 昆蟲於多角度拍前移動時，優先拍背面（自上而下），其攜最多之鑑定信息。一張銳利之背面照優於多張模糊之圖。昆蟲於任何照片前即飛走時，立即憑記憶繪其體形並錄其色。

步驟四：記行為與互動

行為觀察添生態之價，此照片所不能捕。

Behavioral Notes:
+--------------------+------------------------------------------+
| Category           | Record what you observe                  |
+--------------------+------------------------------------------+
| Activity           | Feeding, flying, resting, mating,        |
|                    | ovipositing (egg-laying), burrowing,     |
|                    | grooming, basking                        |
+--------------------+------------------------------------------+
| Movement           | Crawling, hovering, darting, undulating   |
|                    | flight, walking on water, jumping        |
+--------------------+------------------------------------------+
| Feeding            | What is it eating? Nectar, pollen, leaf   |
|                    | tissue, other insects, dung, sap?        |
+--------------------+------------------------------------------+
| Interactions       | Other insects nearby? Being predated?     |
|                    | Ants attending? Parasites visible?        |
+--------------------+------------------------------------------+
| Sound              | Buzzing, clicking, stridulation (wing or  |
|                    | leg rubbing)? Silent?                    |
+--------------------+------------------------------------------+
| Abundance          | Solitary individual, a few, many (swarm,  |
|                    | aggregation)?                            |
+--------------------+------------------------------------------+
| Duration           | How long did you observe?                 |
+--------------------+------------------------------------------+

預期： 至少三項行為觀察：活動、移動模式、豐度。

失敗時： 昆蟲短暫相遇（如落下即飛）時，錄所觀察者並註觀察時長。即「停於葉面、獨居、近則飛、觀察時長 5 秒」亦為有用之數據。

步驟五：初步鑑定至目

不必鑑定至種。置昆蟲於其目即大幅縮鑑定，有助公民科學之審者。

Quick Key to Major Insect Orders:

1. Count the legs.
   - 6 legs → insect (proceed below)
   - 8 legs → arachnid (spider, tick, mite) — not an insect
   - More than 8 legs → myriapod (centipede, millipede) — not an insect
   - Wings but hard to count legs → likely insect; look at wings

2. Examine the wings.
   - Hard front wings (elytra) covering body → Coleoptera (beetles)
   - Scaly wings, often colorful → Lepidoptera (butterflies/moths)
   - Two wings + knob-like halteres → Diptera (flies)
   - Four membranous wings + narrow waist → Hymenoptera (bees/wasps/ants)
   - Half-leathery, half-membranous front wings → Hemiptera (true bugs)
   - Large, transparent wings + long abdomen → Odonata (dragonflies/damselflies)
   - Straight, narrow, leathery front wings → Orthoptera (grasshoppers/crickets)
   - No wings, laterally flattened, jumps → Siphonaptera (fleas)
   - No wings, pale body, in wood or soil → Isoptera (termites)

3. If unsure, note: "Order uncertain — resembles [description]"

預期： 初步鑑定至目（如「Coleoptera — 甲蟲」），或誠實之「目不確定」附物理描述。

失敗時： 昆蟲不明合任何目之快鍵時，錄其體形、翅類、足數。iNaturalist 等平臺接受「Insecta」為初步鑑定，社群鑑定者將精之。誠實之「未知」恆優於勉強之猜。

步驟六：提交至公民科學平臺

上傳目擊至平臺，專家與社群鑑定者可驗並精其鑑定。

Submission Checklist for iNaturalist (or equivalent):

1. Upload photographs — start with the best dorsal shot
2. Set location — use the map pin or enter GPS coordinates
3. Set date and time of observation
4. Add initial identification (order or family if known; "Insecta" if not)
5. Add observation notes:
   - Habitat and microhabitat
   - Behavior observed
   - Approximate size
   - Any sounds produced
6. Mark as "wild" (not captive/cultivated)
7. Set location accuracy — use the uncertainty circle to reflect GPS precision
8. Submit and monitor for community identifications

Data Quality Tips:
- Observations with 3+ photos from different angles get identified faster
- Including habitat context in one photo helps remote identifiers
- Adding a size reference dramatically improves identification accuracy
- Responding to identifier questions speeds up the process
- "Research Grade" status requires 2+ agreeing identifications at species level

預期： 完整觀察已提交至公民科學平臺，含照片、位置、日期、初步鑑定，備社群審查。

失敗時： 野外無網路可用時，先存照片與筆記於本地，擬後上傳。多數平臺允後補提交。若無帳號，存於個人日誌——數據仍有價於己之學習，後可上傳。

驗證

• 於近昆蟲前已錄日期、時間、精確位置
• 天氣與生境背景已錄
• 至少三張照片由不同角度拍之
• 至少一張照片含比例參考
• 行為與活動已記
• 已試初步鑑定至目（或誠實標為未知）
• 觀察已提交至公民科學平臺或存於結構化日誌

常見陷阱

• 近得太速：多昆蟲逢速近則逃。緩動而勿投影於之。先由遠而拍，後漸近之
• 忽生境背景：白牆上之昆蟲照失其生態背景。恆至少一張原地照示其自然環境
• 賴單張照：一張圖常不足鑑定。翅紋、足構、觸角或唯自特定角度可見
• 忘比例：無大小參考，5 mm 甲蟲與 50 mm 甲蟲於照中或同。恆含硬幣、尺、手指作比例
• 勉強鑑定：於公民科學平臺提交信心雖足然誤之鑑定，為研究者製噪音。「Insecta」或「目未知」恆可接受，勝於錯之屬種
• 不錄否定：「乳草叢中未見昆蟲」為調查之有價缺席數據。錄所查者，非僅所得者

相關技能

• identify-insect — 需超初步目級定位時之詳細形態鑑定程序
• observe-insect-behavior — 為深入行為研究之結構化倫理觀察協議
• collect-preserve-specimens — 需實體標本以作最終鑑定時
• survey-insect-population — 將個別目擊擴為系統之種群調查
