Insect collecting Insect collecting has left traces in European cultural history, literature and songs (e.g., Georges Brassens's "La chasse aux papillons" ("The Hunt for Butterflies")). The practice is still widespread in many countries, and is particularly common among Japanese youths. Insects are passively caught using funnels, pitfall traps, bottle traps, malaise traps, flight interception traps and other passive types of insect traps, some of which are baited with small bits of sweet foods (such as honey). Different designs of ultraviolet light traps such as the Robinson trap are also used by entomologists for collecting nocturnal insects (especially moths) during faunistic survey studies.
Scarce swallowtail the purpose of camouflage. The green pupae develop on host plants and develop directly while brown pupae enter into diapause in the leaf litter. Pupating larvae tend to form green pupae before August while after August they tend to form brown pupae. Duration of the or light period appears to be the mechanism which dictates the path of development of the pupa. The results suggest that the green pupa develop on food plants to avoid predation by small mammals and visual avian predators while the brown pupa develop on leaf litter to avoid avian predators.
