Class INSECTA
We have found representatives of only 10 orders that have preyed on or parasitized cockroaches: Beetles, flies, bugs, ants, wasps, stylops, and cockroaches occurred in nature; the others resulted from feeding cockroaches to captive insects or were laboratory observations.
Order ODONATA
Family AESHNIDAE
Anax strenuus Hagen
Common name.—Giant Hawaiian dragonfly.
Experimental prey.—Cockroaches, Hawaii (Williams, 1936): The dragonfly nymph was fed with medium large cockroaches and other insects.
Order BLATTARIA
In this chapter the relations of other arthropods to cockroaches are either as parasites or as predators. Certain cockroaches have turned the tables on their adversaries and become predators themselves. This aspect of cockroach behavior is discussed in chapter XVI. Other associations of cockroaches, as commensals with other insects and as associates of other cockroaches, are discussed in chapters XV and XVII.
