June bug is the common name for scarab beetles that appear around June in temperate parts of North America. June bugs belong to the family Scarabaeidae which currently consists of over 30,000 species worldwide. June bugs are usually brown, rusty, or black, without patterns such as spots or stripes, and rather hair beneath. They are nocturnal and are attracted to lights at night. They have distinctive, clubbed antennae. The front legs of many species are broad and adapted for digging. In some groups, males, and sometimes females, have prominent horns on the head or pronotum to fight over mates. June bugs feed of foliage and flowers at night, sometimes causing considerable damage. Each female buries between 50 to 200 small pearl- like eggs in the soil. After three years of feeding on plant roots, the larvae emerge as adults in late summer and then bury themselves again for the winter. In the spring the adults emerge once more and feed on available foliage. Adults live less than one year. Grubs are a pale yellow or white coloration. The grubs mostly live underground or under debris so they are not exposed to sunlight. Grubs can destroy crops and can kill lawns by severing the grass from its roots.
