Explanation of Names
Liorhyssus hyalinus (Fabricius 1794)
1 NA sp. (1)
5.5-7.5 mm(2)(3)
color extremely variable; can be distinguished from similar rhopalids by the following combination:
antennomere IV ca. 1.5 times as long as III, and distinctly wider
wing membrane considerably protruding behind abdomen (for at least the length of the apical segment)
last abdominal segment with white margin dilated medially and laterally, or with 3 spots (vs dark median band)
widely dist. across NA, most common in sw US - Map (1)(4)(5), cosmopolitan(6)
The fact that the species is listed as having a "cosmopolitan distribution" and "migrant" by some and that it occurs in places like "Africa, Asia, Europe, Australia, Hawaii, Midway Atoll, Mexico to South America, and the West Indies"(1) makes me somewhat inclined to disagree that the species is native in Canada and the continental US. This is definitely an interesting biogeographic anomaly. Maybe it should be considered a "cryptogenic" species (species of uncertain origin) in North America. --E.R. Hoebeke, pers.comm. to =v=
extremely polyphagous, prefers Asteraceae(7)(3)
can damage pistachio fruit and sorghum in the US and many other crops elsewhere, incl. cotton, tobacco, cereals and legumes(6)
