What's That Bug? does not endorse extermination

What R These?
July 13, 2009
Hi
These are found on one paticular plant right now which they feed upon and become intimate as well. I’ve included a pic of the plant. The beetles are1/2″ in length at most. I have never seen these in the field that I walk on a regular basis for the past 5 years. Are they new to this area. Thanks

Hi Yeffer,
The Common Red Soldier Beetle, Rhagonycha fulva, is, according to BugGuide:  “well-established in British Columbia and Quebec [Pat Bouchard]; recently recorded in Ontario from BugGuide photos … native to Eurasia; introduced to North America some time ago.”  BugGuide also indicates:  “adults feed on small insects that visit flowers larvae feed on snails, slugs, and ground-dwelling insects” and especially interesting, that it is also called Hogweed Bonking Beetle. ”  The Garden Safari website indicates it is because “The Hogweed Bonking Beetle (Rhagonycha fulva) is often seen in copula on plants and flowers.”
