Malaise Traps

The Malaise Trap was introduced to the entomological community in the 1930s by Swedish entomologist Dr. René Malaise.  The Malaise trap is an insect flight intercept trap, usually in a tent-like structure with a sloping roof and vertical baffles of mesh netting that channels flying insects, particularly those in orders Hymenoptera and Diptera, into a collecting bottle filled with a preservative solution.
