|Iridopsis humaria |
common name Small Purplish Gray
No information available; presumably deciduous or mixed wood boreal forest in Alberta.
Data unavailable. Adults generally fly in June (McGuffin 1977).
Very similar externally to other members in this genus. McGuffin (1977) states that the conspicuous gray patch on the underside forewing apex present in ephyraria is absent in humaria. For Genitalic differences refer to McGuffin (1977).
Formerly placed in the genus Anacamptodes (Scoble 1999).
The larva is briefly described and figured by Wagner et al (1999). The finely striped, brown dorsum, and black bordered, yellow-green sides make this one of the most distinctive loopers. This is apparently a rather rare and local species throughout its range.
Known from few localities in AB, but there are no obvious conservation concerns.
Prentice (1963) lists only one collection from white birch, suggesting this is either a rare species or that it does not regularly feed on trees and shrubs. Rindge (in McGuffin,1977) lists an interesting array of hosts, including cranberry and dewberry, a number of hardwoods such as hickory, oak, pecan, and herbivorous plants such as asparagus, clover, goldenrod and soybean. Its hosts in western Canada remain to be established.
Texas and Florida north to Nova Scotia and northeastern Alberta. The sole Alberta record to date is one for Fort McMurray (McGuffin 1977).
