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 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.
