Allocyclosa bifurca
Bifurcate Trashline Orbweaver, Forked-tail Trashline Orbweaver
Allocyclosa bifurca is a small orb-weaving spider and the sole species in its genus. Adult females measure 5.1–8.5 mm in body length and are silvery or white in color. The species is distinguished by a forked (bifurcate) projection at the rear of the abdomen—two humps shaped like the letter 'M'—giving it the Latin name meaning 'two-forked.' This is the only Cyclosa-like species north of Mexico with this forked tail structure. The spider exhibits remarkable camouflage behavior, arranging debris and egg sacs in a vertical line through its web to masquerade as bird droppings. Unusually, males are rarely observed, and females possess vestigial external genitalia with no external opening, suggesting possible parthenogenic reproduction. The species is also notable as a host for parasitic wasps that chemically manipulate its web-building behavior.
Nelphe carolina
little Carol's wasp moth, Florida eucereon
Nelphe carolina is a moth species in the subfamily Arctiinae, first described by Henry Edwards in 1887. It is known from southern Texas, Florida, Mexico, and Cuba. Adults have a wingspan of 31–34 mm and have been recorded on wing year-round. The larvae feed on Cynanchum species. The species is also known as the Florida eucereon or little Carol's wasp moth, and is currently placed in the genus Nelphe, though it was formerly treated under Eucereon.
