Among Lampyridae, what is described about the elytra?

• A. Elytra are hard and protective
• B. Elytra are soft and flexible
• C. Elytra are iridescent only
• D. Elytra are absent in females

Answer: (B)

In Lampyridae, the forewings (elytra) are soft and flexible. This lighter, less hardened covering still protects the hind wings when at rest, but it isn’t as rigid as in many other beetles. That softness is a distinctive trait of fireflies, reflecting a different level of sclerotization than the typical hard, protective elytra seen in many beetles. The other ideas aren’t as accurate: elytra aren’t universally hard and protective in this group, iridescence isn’t exclusive to lampyrids, and while some females may be wingless or have reduced wings, elytra aren’t completely absent in females across the family.
