Alaus myops
Small-eyed Click Beetle, Blind Click Beetle
Alaus myops, commonly known as the Small-eyed Click Beetle or Blind Click Beetle, is a large elaterid beetle distinguished by its reduced eyespots compared to its congener A. oculatus. Adults are primarily slate gray in coloration and active in southern pine forests. The species exhibits the characteristic clicking mechanism of the family Elateridae, using a prosternal spine and mesosternal notch to launch itself when disturbed. Both adults and larvae are predatory, inhabiting loose bark on pine trees, logs, and stumps.
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.
Alberada
Alberada is a genus of snout moths described by C. Heinrich in 1939. It belongs to the subfamily Phycitinae within the family Pyralidae.

Aleptina aleptivoides is a small noctuid moth described from North America in 1912. The species belongs to the subfamily Condicinae, a group of generally inconspicuous moths with limited ecological documentation. Available records suggest it occurs in arid and semi-arid regions of the southwestern United States and adjacent Mexico. The specific epithet "aleptivoides" references its resemblance to the related genus Aleptina, indicating taxonomic confusion or similarity at the time of description.
Aleptina junctimacula
