Fret not indigenous beetle-lovers, the harlequin flower beetle is the answer to your prayers! In contrast to invertebrates like roaches and isopods, beetle care tends to be a bit more complex. Care must be taken to craft the proper substrate and attention given to each step of the beetle’s life cycle (particularly pupation) to ensure a healthy, vigorous adult emerges. Among the scarab beetles and their closest relatives, the harlequin flower beetle is certainly the easiest to rear. Larvae are vigorous eaters of rotten wood, grass clippings, yard refuse, and general compost, provided the substrate mixture is easy to maneuver through and not overly wet or dry. Unlike many beetles which require additional accommodations during their pupal phase, harlequin flower beetle larvae are quite content to construct pupal cells out of their own frass. The gorgeous beetles emerge several weeks after pupation and are day-active as long as fruit is provided. It is extremely satisfying to watch dozens of the black and yellow adults swarm a piece of soft banana!
