Collecting and Preparing Microlepidoptera

Collecting and Preparing Microlepidoptera. Collecting methods – just like big moths!. 1. Blacklighting (sheet or trap) – most species 2. Pheromone trapping – diurnal species or target species 3. Aerial nets – diurnal species (dusk-flyers) 4. Rearing – sedentary or target species.

  1. Collecting and Preparing Microlepidoptera

  2. Collecting methods – just like big moths! 1. Blacklighting(sheet or trap) – most species 2. Pheromone trapping – diurnal species or target species 3. Aerial nets – diurnal species (dusk-flyers) 4. Rearing – sedentary or target species

  3. Collecting methods 1. Blacklighting Trap – specimens can get chowdered Sheet – more selective method Need to have a supply of small “killing jars” and a “dump jar.” Or a supply of snap-top vials; put in freezer over night.

  7. Pinning • minutensfor tiny specimens.

  8. Pinning • minutensfor tiny specimens. • place specimen on foam (or soft wood) surface, dorsum up.

  9. Pinning • minutensfor tiny specimens. • place specimen on foam (or soft wood) surface, dorsum up. • using forceps, pin specimen in middle of thorax, perpendicular to dorsal surface. ↓

  10. Spreading No two people use exactly the same equipment or techniques. • Tiny spreading boards. • Small blocks. • Plastic boxes with plastozote (foam).

  11. Spreading

  12. Spreading

  13. Spreading (double mounting)

  14. To prevent specimens from becoming too dry • Spread microlepidoptera first. • Keep humidified in “relaxing jar.”
