Order Orthoptera (grasshoppers, crickets, katydids)

11. DIFFERENTIAL GRASSHOPPER, Melanoplus differentialis (Thomas)(Orthoptera: Acrididae). Nymphs and adults can be collected with a sweep or aerial net. Nymphs should be preserved in alcohol while adults (with fully-developed wings) should be killed and mounted on insect pins.

15. KATYDIDS AND LONG-HORNED GRASSHOPPERS, many species (Orthoptera: Tettigoniidae). 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. Wingless immatures should be preserved in alcohol.

16. TREE CRICKETS, Oecanthus spp. (Orthoptera: Gryllidae (Oecanthinae)). Tree crickets can be collected by sweeping tall weeds with a sweep net or by beating branches of trees onto a drop cloth. Adults can be killed, pinned and mounted. Immatures should be preserved in alcohol.

17. FIELD CRICKETS Gryllus spp. (Orthoptera: Gryllidae (Gryllinae)). Crickets can be found under piles of decaying plants in the garden, in the lawn or around fields (see L-1311). At times of the year, they are attracted to lights in large numbers. They can be killed by freezing or with a killing agent and mounted on an insect pin.

19. SOUTHERN MOLE CRICKET, Scapteriscus borellia Giglio-Tos (Orthoptera: Gryllotalpidae). Adults are attracted to lights at night, particularly in early summer, where they can be collected, killed by freezing or in a jar containing poison (e.g., ethyl acetate) before being mounted on an insect pin. Nymphs and adults can also be killed and preserved in alcohol. Adults and nymphs can also be driven out of infested turfgrass by sprinkling a 2 by 2 ft. area with a solution of 1 fl. oz. liquid dishwashing detergent in 2 gallons water.
