Malaise traps are used for the collection of flying insects - particularly wasps (hymenoptera) and flies (diptera). The trap consists of a tent-like structure with a collection head situated at the highest point. Insects fly into the screen and migrate upwards where they are collected in a plastic bottle, ready for examination. When used alongside trays the traps can also be used to collect other insects such as beetles which fall to the ground when they hit the trap.
