Anavitrinella pampinaria  (Common Gray)
Field Marks

Whitish gray wings, with variable amount of brown shading. PM line sinuous, AM line is quite straight near inner margin. Discal spot on HW may be present or absent--if present, NOT hollow. Prominent white band at top of abdomen. Males have very prominent and large fovea at base of FW. Iridopsis does not have fovea, but Stenoporpia does.

   

Unfortunately, this species can look so similar to Stenoporpia polygrammaria that they are nearly indistiguishable. In my opinion the best character is the conspicuous white stripe on the first abdominal segment, which polygrammaria lacks. This stripe is sometimes faint, but it is always present. Iridopsis ephyraria can easily be separated by its hollow discal spot on the hindwing.Worn specimens are common and can be rather tricky to identify, but happily the lack of scales usually makes the fovea much more visible.


TAXONOMY NOTE:
This genus was misspelled as 'Anavitrinelia' in the Hodges et al 1983 MONA checklist but corrected in Parsons et al 1999.


Range

Distribution pattern: Transcontinental.
This moth is reported to occur from southern Canada south to mexico, and coast to coast in the US (McGuffin 1977,Forbes 1948), although published records are hard to find south of Canada.

The range of atristrigaria is very poorly known, and we cannot be certain at this point that it doesn't extend further northward.
