Explanation of Names
Euderces LeConte 1850
4 spp. in our area, ~60 total(2)
4‒9 mm
among the smallest of our longhorns; ant-like and often attractively marked(3)
among the three eastern species, E. pini is the only one with the post-median elytral fasciae in deep grooves; the median fascia are oblique in E. picipes vs. transverse in E. reichei (T.C. MacRae, 21.iv.2008)
Paraphrasing iNaturalist discussion:
reichei seems to be sparsely punctate/granulate
pini is longitudinally rugose, but does not reach anterior margin
picipes is longitudinally rugose and is extended to reach anterior margin
Pattern of vitta (stripes) on elytra:
pini has a transverse discal vitta as well as a basal/lunule vitta
picipes and reichei just have the discal one
picipes seem to be slanted where as reichei is not
se. Canada (QC‒ON) to Venezuela‒Colombia(4)(2)
Larvae feed in dead branches of chestnuts, hickories, oaks, redbuds, hackberries, etc.(3)
