Alaus oculatus
Eastern Eyed Click Beetle, Eyed Elater
Alaus oculatus, commonly called the eastern eyed click beetle or eyed elater, is a large, striking click beetle native to eastern North America. Adults reach 25–45 mm in length and are immediately recognizable by the prominent false eyespots on their pronotum—large oval patches of dark scales framed in white that function in predator deterrence. The beetle possesses a remarkable clicking mechanism: a prosternal spine and mesosternal notch that, when flexed and released, produce an audible snap capable of launching the beetle several inches into the air. This behavior serves both defensive and righting functions. The larvae are predatory wireworms that inhabit decaying wood, feeding voraciously on other beetle larvae, particularly cerambycids.
Castianeira cingulata
twobanded antmimic, two-banded ant-mimic sac spider
Castianeira cingulata is a small ant-mimicking spider in the family Corinnidae, commonly known as the twobanded antmimic. Females measure 7–8 mm in body length, males 6–7 mm. The species exhibits Batesian mimicry of carpenter ants through coloration, body shape, and behavioral displays including bobbing movements and foreleg waving that simulates antennae. It inhabits woodland leaf litter across eastern North America, where it hunts insect prey.

black firefly, woodland lucy
Lucidota atra is a diurnal firefly species in the beetle family Lampyridae, native to eastern North America. Unlike most fireflies, adults are active during daylight hours and lack functional light organs. Males locate females using pheromone-sensing antennae rather than bioluminescent signals. The species completes its life cycle in moist woodland habitats, with bioluminescent larvae preying on soft-bodied invertebrates.
Rainieria
A genus of stilt-legged flies (Diptera: Micropezidae) containing at least 20 described species. Members are characterized by their elongated legs and slender bodies typical of the family. The genus has a Palearctic distribution with records from Europe and Asia, including recent discoveries in South Korea. Some species, such as Rainieria calceata, are considered rare and endangered with limited dispersal capabilities.
Temnostoma daochus
Yellow-spotted Falsehorn
Temnostoma daochus is a rare syrphid fly species in the eastern United States, notable for its elaborate Batesian mimicry of solitary mason wasps. It exhibits both morphological and behavioral mimicry, including darkened wing edges that imitate vespid wing folds and deliberate foreleg movements that mimic wasp antennae. The species is closely related to T. barberi, with which it forms a lineage sister to the rest of the genus. Larvae develop in moist decayed wood.
Xylomya terminalis
Xylomya terminalis is a species of wood soldier fly in the family Xylomyidae, described by Vasey in 1977. The species is known from the eastern United States, with records from Vermont and other states. Xylomyidae are predatory flies whose larvae develop in decaying wood and under bark. Adults are typically found in woodland habitats.
