scientific name    Perillus exaptus    

habitat
This species is known from grassy marshlands, flatlands and under stones (McPherson 1982).

seasonality
Strickland Museum collections date from May to August; Blatchley (1926) reported collections into October.

identification
The species is fairly oval shaped with a brightly coloured cuticle, though coloring is apparently highly variable. The pronotum is prominently red coloured posteriorly, pale-yellow anteriorly, and has a wide, transverse black bar antero-medially. The presence of this bar distinguishes this species from the morphologically similar P. bioculatus. Perillus exaptus can also be isolated from P. bioculatus due to the presence of ventral tubercles that are not longer than their width on the fore-femora. The scutellum is mostly black with narrow, yellow lateral bands that follow its margin apically. The hemelytra are black with lateral margins, embolium, also pale yellow, and the membranous regions lacking pigmentation. Connexivum are concealed under the wings. The species is small in comparison to P. bioculatus; length between 5 and 7.5 mm (Blatchley 1926; McPherson 1982).

life history
Life history is unknown.

conservation
Blatchley (1926) reports that it is rare at all of its recorded localities.

diet info
The dietary information for this species is unknown. Despite the fact that it is a predatory insect, no prey species have been recorded (McPherson 1982).

range
Collections have been recorded across Canada, from British Columbia to Newfoundland, excluding Prince Edward Island (Maw et al. 2000), and south as far as the southern limits of the United States along the Pacific coastline. In the east, its southerly distribution ends in New Jersey (Henry and Froeschner 1988). In Alberta, specimens have been collected between the northern and southern limits of Edmonton and Cypress Hills Provincial Park, respectively.
