Alobates pensylvanica (False Mealworm Beetle).
Size: approx. 20 mm. Photo: 04/12/16, 9 pm.

Usually found under decaying bark in forests, the predatory False Mealworm Beetle is also attracted to lights at night. Its pronotum is almost square and the elytra have rows of fine punctures. The sister species A. morio is very similar, but rarer and has a tuft of yellow hair on the mouthparts. The species name is sometimes spelled "pennsylvanica".

Merinus laevis.
Size: approx. 20-25 mm. Photo: 03/20/20, 1 am.

After an evening of no new bugs at our porch light, I went to the bedroom and found this specimen of Merinus laevis crawling over the carpet. Although I was quite tired, I took a couple of pictures and released it to the outside. M. laevis is quite similar to Alobates (see above), but the dotted lines on the elytra are absent or less pronounced.

This long-jointed beetle is Statira basalis. It can be found mainly in the Southern states and Texas and seemingly is most frequent during the spring months. The genus has 15 species in the US. S. basalis can be identified by the pale yellow color of the basal half of their femora and coxae.

This Darkling Beetle was attracted to our porch light. It lives on broad-leaved trees (e.g. oaks) and is rather common in our area. This particular specimen is a rare color variation that has bright red or orange legs (rather than the usual black ones). This variation occurs only in the Southeast.
