Calosoma scrutator Fiery Searcher
An active predator, Calosoma scrutator roams relatively moist places looking for caterpillars and other prey amongst plants, leaves, and debris. In addition to the metallic green elytra and the golden edging the rest of the beetle, apparently black, picks up various shades of purple, red, green, etc. in direct light much in the manner of a drop of oil on the surface of water. These beetles live a year or more and are quite hardy captives readily accepting mealworms, crickets, and most other commonly available live foods.
