Biological
Data: The life history of Valgus seticollis is
probably similar to Valgus canaliculatus. Adults and larvae
are found in wood infested with termites such as Reticulitermes
flavipes (Kollar). Specimens have been collected from oak (Quercus
sp.), Pitch Pine (Pinus rigida), American Chestnut (Castanea
dentata) and Tulip trees (Liriodendron tulipifera), and
from a strawberry plant. Colonies usually contain a majority of females,
although colonies have been observed with males and females in almost
equal numbers.
