darkling beetle

5968 Dear Sirs,  My name is Mellissa and I live in Jamaica. A cemetery is nearby and the house is in between two open lots with mostly shrubs. Our yard has grass and some fruit trees. We also use soak-away pits/cesspools that allow water to absorbed into the earth. There is also a shed in the back yard that was once a haven for cockroaches. Is is sunny all year round here with rainy and dry seasons – the bugs are here irrespective. These bugs/beetles come out in the night through small spaces in our windows, in the daytime there in minimal movement and sometimes they appear dead when they are not. They are about a quarter of an inch long, black, have six legs and a set of antlers/feelers. They have a semi-hard exoskeleton and if you step on one you can hear it crack. They are quite a pest and I would like to know what they are and what they exist to do. Please let me know if you need any further information.   Thank you

This might be a darkling beetle (Coleoptera: Tenebrionidae), but I cannot see enough detail (particularly its tarsal segments) to be certain. Although these may be nuisances, at least it does not appear to be any of the common pest species in that family. Ed Saugstad, retired entomologist; Sinks Grove, WV.
