Description |
Adults are 3 ⁄16″ to ⅝″ (5.5 to 15.0 mm) in length. The outer lower mouth parts (galeae) are greatly elongated into a sucking tube, allowing the beetles to drink flower nectar. On the front and middle legs the last part of the leg (tarsus), corresponding to the foot, has five segments. On the hind leg the tarsus has only four segments. The claw at the end of the tarsus is comb-like. |
