Scarabaeidae (Part 2)

As promised, here is the other representative of the scarab family that I have collected - two specimens, one wings spread, the other wings closed. They were both found around twilight, are not known to bite, and are approximately 1cm to 1.5cm long, and 7 mm wide.

Coleoptera; Polyphaga; Scarabaeoidea; Scarabaeidae; Dynastinae; Cyclocephalini; Cyclocephala lurida
Common Name: Southern Masked Chafer

Masked Chafers are beetles native to North America, and an agricultural pest across the country, though is most common in the southern states. They tend to be a dull yellow-orange color, with a dark head. Their distinguishing characteristics as a genus include a rounded clypeus (frontal mouth plate) and a relatively large fifth foot segment, or tarsomere. The species attack the roots of plants, particularly turfgrasses. The larvae are large white grubs, about 8 mm long, and gradually darken to a reddish color before they pupate into adult beetles.
