Ploiaria
Scopoli, 1786
thread-legged bugs
Ploiaria is a of thread-legged (: Emesinae) comprising approximately 130 described . Members are characterized by extremely slender, elongated bodies and legs. The genus exhibits remarkable variation in development, with species displaying macroptery, brachyptery, or complete aptery. Several species are , including P. domestica, which has adapted to human dwellings.

Identification
Distinguished from other Emesinae by the combination of: lacking spine-like ; prosternal margin emarginated medially; posterior pronotal lobe abbreviated, covering only the extreme base of the ; absence of spines on and ; profemora without the bearing several spine-like setae found in some related genera; and three-segmented protarsi. The variable condition within can complicate identification.

Habitat
Occupies diverse environments from tropical forests to deserts and oceanic islands. Microhabitats include arboreal situations (trees, epiphytes), ground-level substrates (leaf litter, under stones), and cryptic spaces (under bark). Some have colonized human-made structures; P. chilensis and P. domestica are documented synanthropes. Oceanic island presumably established through rafting on floating vegetation.
Distribution
distribution spanning tropical, subtropical, and temperate regions worldwide. Present on oceanic islands. Individual have more restricted ranges; for example, P. anak occurs in the Pune District of India.
Diet
Predatory. Documented includes Phlebotomus , mosquitoes (), and ().
Ecological Role
in terrestrial , contributing to of small flying and jumping insects. Arboreal and ground-dwelling occupy different trophic positions within stratified structures.
Human Relevance
P. domestica and P. chilensis are , occurring in human dwellings. Potential as agents of pest and , though not documented as commercially utilized.
