Was walking to the store for groceries and observed this guy. Never seen one like him, weird bugs are uncommon here. What is it?
We are quite certain that if you looked a bit more closely, you would find many “weird bugs” in Buenos Aires. This is a Longicorn or Longhorned Borer Beetle from the family Cerambycidae, and we quickly identified it as Retrachydes thoracicus on the Insectos de Argentina y del Mundo site. Cerambycoidea.com indicates the species is found in: “Brazil, Bolivia, Paraguay, Uruguay, Argentina.” BioLib has an excellent image of a pinned specimen and Meloidae.com has several nice images of living individuals. Beetles in the Bush indicates: “Of course, it is a species of longhorned beetle (family Cerambycidae) that apparently is found commonly in South America.”
