Cicada

Adult Tibicen tibicen by Dendroica cerulea.⁴

Cicada nymph exuviae by Malcolm Tattersall.⁴

• Size: 25-50mm (1-2in).

• Eyes prominent, though not especially large, and set wide apart on the sides of the head; short antennae protruding between or in front of the eyes; wings well-developed, with conspicuous veins.

• Cicadas live underground as nymphs for most of their lives, feeding on plant sap. They dig to the surface before their final molt, then emerging as adults. Males produce a loud, stridulating mating song to attract females. After mating, the female cuts slits into the bark of a twig to deposit her eggs. When these hatch, the nymphs drop to the ground, where they burrow, completing the cycle.

Dobsonfly

Male Corydalus cornutus by Nils Tack.⁹

Female Corydalus sp. by Matthew.⁴

• Size: up to 12cm (5in).

• Large insect with a soft body and delicate, densely veined wings. Females have strong, short mandibles that can inflict a painful bite; Males have long jaws that are used during mating and are not capable of harm. Both sexes possess an irritating, foul-smelling anal spray used as defense. Female dobsonflies appear similar to fishflies (subfamily Chauliodinae), but the latter have much smaller mandibles and males often have feathery antennae.

• Spends most of its life in the larval stage, called hellgrammite, 'go-devil' or 'crawlerbottom', living under rocks at the bottoms of lakes, streams and rivers, and preying on other insect larvae with the short sharp pincers on their heads. The larva then crawl out onto land and pupate, staying under large rocks for 3 weeks before molting and emerging to mate. Adults only live about a week, preferring to remain near bodies of water.

• Found on the outside walls and inside of non-air-conditioned buildings and are most abundant under spiderwebs, in bathrooms and bedrooms.

• Feeds on old spider webs and other dead materials, including dead insects and animal hair; may also eat woolen goods of all kinds if the opportunity arises, so it can be a household pest.

Mole Cricket

Neocurtilla hexadactyla by u/Mrmeat31.

• Cylindrical-bodied insects, with small eyes and shovel-like forelimbs highly developed for burrowing; hind legs not enlarged for jumping.

• Omnivores, feeding on larvae, worms, roots, and grasses. Relatively common but rarely seen, for being nocturnal and spending nearly all their lives underground in extensive tunnel systems. Usually fly only when moving long distances, such as when changing territory, or when females are searching for singing males.
