Trimerotropis verruculatus verruculatus Vickery, Johnstone, & Kevan 1974
Occasionally found with Circotettix rabula along the north edge of the prairies, which has wings more ample and broader, and hind wings with more main radial veins strongly thickened and with the connecting venlets more obvious and parallel, creating rows of narrow rectangular cells. The dark band is usually not well developed (almost missing to translucent) and most of the tip of the wing is usually transparent. The hind tibiae varied in color, but mostly yellowish to blueish (usually brownish or blackish in subspecies verruculata). Circotettix are even louder.
Mostly in Canada from the Yukon and n. British Columbia east to the Atlantic. Mostly in the southern Boreal forest region; north of the Plains grasslands and south of the Tundra. Enters the northeastern US from Minnesota to Pennsylvania.
Mostly exposed, often rocky areas. Sometimes also in disturbed open areas and along paths and road cuts.
summer to first hard frosts
overwinters as eggs laid in the ground.
Subspecies suffusa is similar, but occurs in mountain forest areas from the Rockies westward in sw. Canada and the western US. The two meet in Alberta, where they apparently blend in a narrow contact zone. Ssp. suffusa is usually darker and plainer looking and the wings are a bit narrower with the main veins a bit less swollen and with the outer part of the wing usually blacker. They behave basically the same and favor the same habitats.
These species and related ones will probably be moved out of Trimerotropis (again) and either back into Circotettix (to which they are most closely akin) or into a new genus of their own. However, for now, they are called Trimerotropis.
