Collecting and Preparing Microlepidoptera

Collecting methods – just like big moths!

1. Blacklighting (sheet or trap) – most species2. Pheromone trapping – diurnal species or target species3. Aerial nets – diurnal species (dusk-flyers)4. Rearing – sedentary or target species

Collecting methods

1. BlacklightingTrap – specimens can get

chowderedSheet – 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.

techniques. Tiny spreading boards.Small blocks.Plastic boxes with plastozote (foam).

To prevent specimens from becoming too dry

Spread microlepidoptera first.Keep humidified in “relaxing jar.”
