A Malaise trap like this one is an easy way for entomologists
to take a survey of the insects flying in the area.
Basically a mesh tent thats open at the bottom,
the Malaise traps design takes advantage of an
insects natural tendency to fly upward when startled.
When insects enter the trap, they fly up and are funneled
toward a jar of ethyl alcohol. Knocked out and preserved
by the alcohol, the insects form a soup of species that
researchers can sort through and study.
tangible census, this insect “soup” from
a Malaise trap equals hours of potential information
gathering for an entomologist.
