May Beetles are a frequent visitor during summer evenings, bumping into windows and hanging out in groups.
May Beetles are also called Junebugs as they are particularly active and visible during this month across most of the continent. There are many species in the Phyllophaga genus and they resemble each other in many ways, though some are darker than others. The jointed brown legs are useful when clinging to window screens and door frames.
They tend to bump into windows many times at night, presumably drawn by interior light. They form congregations around porch lights, front doors, back doors, windows and other areas with ambient light.They are not dangerous to people, but they used to be agricultural pests to orchards, groves, sod farms and crops. Their impact on these industries has waned though and most people find them only a nuisance when coming and going through doorways for fear of letting them indoors or smashing them in door jambs.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
