Alydus eurinus (Say)
Orig. Comb: Lygaeus eurinus Say 1825
Explanation of Names
eurinus is likely from Greek eur(o) East; or broad. Possibly from the related Latin eurin meaning the east wind (i.e., eastern?) (1). It seems that either the "broad" sense of eur is the likely origin, since Say's original binomial combination was Lygaeus eurinus, and this would likely refer to the broad-head of this insect in comparison to other members of the then-genus Lygaeus.
