Why are Orthoptera insect orders important?
Orthopterans are important members of nearly all terrestrial ecosystems, both in the role of consumers and prey. Massive outbreaks of some species of grasshoppers (and less frequently katydids and crickets) can cause enormous losses for the food industry and forestry.
How do you collect Orthoptera?
Adults can be collected using a sweep net in weedy areas, a mature rice field or using an aerial net or jar to collect individual specimens from flowers and other plants. Winged forms can be killed (heat, freezing or toxin-containing killing jar) and mounted on an insect pin.
