Large Bloody-nosed Beetle
A somewhat smaller relative of Timarcha tenebricosa, with a similarly rounded, convex, black body and fused wing cases. It shares the characteristic reflex bleeding behavior of its genus.
Did You Know?
Adults are entirely flightless because their hind wings have been completely reduced and their elytra are fused together.
Rose-stem Gall Wasp
A gall wasp that creates spiny galls on the stems of wild roses in North America. Each gall contains a single larval cell surrounded by hard woody tissue.
Did You Know?
Its galls often persist on rose stems for years after the wasp has emerged, serving as shelter for other insects.
