|scientific name Photedes didonea |
Native grassland in the arid grasslands region.
A medium-size moth (approx 3 cm wingspan) with brown forewings and light grey-brown hindwings. The forewings are grey-brown with lighter red-brown in a more or less longitudinal pattern. The most prominent markings are the white strip forming the lower end of the postmedian line, and the narrow blackish streak in the fold between the antemedian and postmedian lines. The forewing fringe is checkered with white at the veins. The antennae are simple and the sexes are alike. A number of Apamea species share a similar color and pattern but are larger and more robust moths.
Almost nothing is known. The adults are nocturnal and come to light. There is a single annual brood, which flies in Alberta in late summer and early fall (August 25-September 7). Bowman (in error?) states it flies in July. The larval hosts are unknown.
A western species, found from extreme southern Alberta south and west at least to Utah Oregon and California. In Alberta (and Canada) it is known only from the Lethbridge and Writing-on-stone areas.
Photedes didonea is one of the many grasslands noctuids that fit well into the "lbj" (little brown job) category. It is one of several moths that, so far as we know, occur in Canada only in extreme southern Alberta. There are old specimen records from the light trap run for many years at the Agriculture Canada Research Station at Lethbridge. More recently Jim Troubridge and I found it during one of our collecting trips to Writing-on-stone Provincial Park.
Recorded in Canada only from Writing-On-Stone Provincial Park and Lethbridge. Didonea was transferred from Xylomoia to Chortodes by Mikkola (1998), and Chortodes was subsequently synonymized by Zilli et al. (2005).
