May Beetles are a frequent front door visitor during summer evenings, bumping into walls and windows instead of using the bell.
May Beetles are also called Junebugs because they are particularly active and visible during that month of the summer 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. A hefty, oblong, brown body has shiny elytra covering mighty wings. Their 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 often 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 in 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.
Scientific Name: Phyllophaga sp.

Size (Adult; Length): 8mm to 25mm (0.31in to 0.98in)
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.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
