|scientific name Eurygaster amerinda |
Found in dry, grassy habitats.
8.5-10.5 mm. The genus Eurygaster is easily told from other Albertan genera by its narrow scutellum, which exposes the hemylytra for its entire length. Both E. amerinda and E. alternata are similar in appearance, although E. amerinda is somewhat larger and is usually found in dry, grassy areas (McPherson 1982). Colour and patterning in both species can be quite variable.
This species overwinters as adults and is univoltine (McPherson 1982).
Phytophagous. This species is known to feed on wild oats (Amsinckia intermedia Fischer and Meyer, Ranunculus californica Bentham) and rye grass (McPherson 1982), but probably feeds on other plants as well.
E. amerinda is found throughout much of Canada and the United States although in Canada no specimens have been recorded in the Yukon nor the maritime provinces (Maw et al. 2000).
