English
fiery searcher
Compound of fiery + searcher.
The story
Fiery comes from the orange colors found around the edge of the abdomen. Searcher is a partial calque of translingual Calosoma scrutator, itself from Latin scrūtātor (‘searcher, examinator, investigator’), which references its diet of certain other bugs, which it hunts to find. Searcher could also reference other species of the genus Calosoma, sometimes known as caterpillar searchers.
Today it means
noun Calosoma scrutator, a common North American ground beetle which has an iridescent exoskeleton, with large parts on its top being green with orange highlights on the abdomen.
