|scientific name Pronoctua craboi |
Open subalpine, near treeline.
Not yet collected in Alberta
A medium-size moth (4.0 cm wingspan) with mottled dull grey and pale yellow-brown forewings and grey-brown hindwings. The forewing pattern is rather blurry, with the yellow-brown most prominent at the antemedian and postmedian lines. The orbicular and reniform are also incompletely outlined in the yellow-brown scales. The antennae are simple and the sexes are similar. Very similar to both P. typica and P. peabodyae. The forewings are more contrasting and the hindwings usually paler than those of peabodeyae, which is usually found at lower elevations. P. typica has slightly paler hindwings, and usually a darker median band. The genitalia of typica are very different, with the valves tapering to a long narrow curved apex (blunt in craboi).
The adults are nocturnal and come to light. Almost nothing else is known about this recently (1998) described moth, which is known from only a handful of specimens.
A widespread but rarely collected species.
A western species, occurring from east central California north to southern British Columbia, and south in the Rocky Mountains to central Colorado.
