Diradius vandykei
Diradius vandykei is a species of webspinner (order Embioptera) in the family Teratembiidae. It was originally described as Oligembia vandykei by Ross in 1944, and later transferred to the genus Diradius. The species is known from North America, with specific records from Florida. As with other embiopterans, it is characterized by the ability to produce silk from glands on the forelegs, which is used to construct protective galleries.

Haploembia
webspinners
Haploembia is a genus of webspinners (order Embioptera) in the family Oligotomidae, containing at least three described species. Native to the Mediterranean region, members of this genus have been introduced and naturalized in California and other areas. These insects are notable for producing silk from specialized glands on their forelegs, which they use to construct protective tunnel systems. Species within this genus exhibit distinct reproductive strategies: Haploembia tarsalis is parthenogenetic, while H. solieri reproduces sexually.

Haploembia solieri
bicolored webspinner
Haploembia solieri is a sexually reproducing webspinner species in the family Oligotomidae, distinguished from the parthenogenetic congener H. tarsalis by its social behavior and smaller genome size. Adults are orange and black, approximately 11 mm in length. The species produces nano-scale silk fibers using specialized silk ejectors on the front tarsi, which they use to construct tunnel systems under bark or in crevices. Originally described from Europe, it has been introduced to North America and recorded from Georgia in the Caucasus region.

Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

Oligotoma saundersii
Saunders' embiid, Saunders' Webspinner
Oligotoma saundersii is a webspinner (order Embioptera) native to southern Asia that has become a widespread invasive species in tropical and subtropical regions worldwide. Adult males possess long narrow wings and are attracted to lights at night, while females are flightless and chocolate-brown in color. The species constructs silken galleries in concealed humid locations and has been introduced to the United States, where its range extends from Texas to Florida.
