Synonyms and other taxonomic changes
Synanthedon chrysidipennis (Boisduval)
Range
Distribution.- At higher elevations from British Columbia south to Utah and California. The type-locality, Los Angeles, is probably erroneous and may simply represent a locale from which the type specimen was sent.
Food
The larvae have been recorded as boring in the roots of Polygonum davisiae and Polygonum sp. (Polygonaceae). Henne notes that several specimens were observed in Smokey Valley, Tulare County visiting flowers of Achillea lanulosa Nutt. (Asteraceae).
Life Cycle
Biology.- Pupation takes place in cocoons in the larval burrow near the crown of the host plant, or the larvae may construct silk-lined tubes extending from the exit hole in the root to the soil surface to provide a means of escape for the mature pupa. Adults can be seen, often in large numbers, from late June through early August flying about the host plants in alpine meadows. -- William H. Taft, 19 August, 2016
