Female Flower Chafer

Dear Jason,
The best we are able to provide at this time is a genus identification.  This is a female Flower Chafer in the genus
Valgus, which we verified by matching your image to this BugGuide image.  According to BugGuide:  “Small compact-shaped (almost tick-like) scarabs that visit flowers. Note short elytra, leaving much of abdomen exposed.”  BugGuide also notes that the habitat is “decomposing wood, usually associated with termites; adults visit flowers” and “Larvae are wood decomposers, usually associated with termite colonies.”  The more research we did, the more confident we are that your individual is a female of an adventive species introduced to North America from the Old World, Valgus hemipterus.  According to the Generic Guide to New World Scarab Beetles:  “Distribution: Palaearctic (Algeria, Europe, Iran, Morocco, southern Sibera and Tunisia) and Nearctic:CANADA: Ontario. USA: Michigan, Ohio.”  The same site also states:  “Adult females are attracted to moist, rotting wood to oviposit, although oviposition has been observed in fairly dry wood and in living trees. Females leave colonized wood to seek out new oviposition sites in early summer and use their pygidial spines to create such sites. The entire life cycle of Valgus hemipterus can be completed within a log, and Nearctic specimens have been taken from rotting wood of the American elm (Ulmus americana L.). Oak, birch, elm, and chestnut are common host trees in Europe.”
