Summary

Berytidae, or stilt bugs, are slender insects primarily feeding on plant sap. They are characterized by their long legs, unique feeding habits, and are commonly found on plants with glandular trichomes, largely distributed worldwide.

Physical Characteristics

Berytidae are extremely gracile insects with very long and slender legs, suggestive of names such as 'thread bugs' or 'stilt bugs'. They typically have brown to yellow coloration and a forward-facing protrusion between the antennae bases. The forelegs resemble their other legs in form and function; they have antennae that are geniculate with a swelling at the tips. The wing membrane contains five veins, and some species have spine-like protrusions on the forewings.

Identification Tips

Distinguished from Emesinae by forelegs that are not raptorial, and by antennae which typically have a more obvious swelling at the tips. The head has a noticeable protrusion between the antennae. Many species also have split or toothed claws.

Habitat

Typically associated with plants that have glandular trichomes, particularly in the families Geraniaceae, Onagraceae, Scrophulariaceae, and Solanaceae. Many of their hosts are eudicotyledonous angiosperms.

Distribution

Worldwide, with over 200 known species; common in North America with 12 species in 8 genera in the local area.

Diet

Mostly phytophagous, feeding on plant sap; some species may feed on mites and small insects, displaying opportunistic scavenging behavior.

Ecosystem Role

Most members are sap-feeders but some engage in facultative carnivory or saprophagy, influencing plant and insect populations.

Health Concerns

Many species can inflict a painful prick on human skin when probing surfaces.

Evolution

The family Berytidae is classified into three subfamilies, indicating a degree of evolutionary divergence among species.

Similar Taxa

Emesinae (though in different families)

Misconceptions

Commonly mistaken for Emesinae due to their long slender forms.
