A leaf litter sieve is a piece of equipment used by entomologists, in particular by coleopterists (beetle collectors) (Cooter 1991, page 7) as an aid to finding invertebrates in leaf litter. A typical leaf litter sieve consists of a gauze with holes of approximately 5 to 10 mm width. The entomologist places handfuls of leaf litter into the ...

The entire bag of the net is generally constructed from a lightweight mesh to minimize damage to delicate butterfly wings. Other types of nets used in insect collecting include beat nets, aquatic nets, and sweep nets. Nets for ...
