Similarly, why do we only see June bugs in June?
It has to do with the short life cycle these bugs have. Eventually they pupate (sort of like how a caterpillar changes into a butterfly, only not as pretty at the end), and become the ugly bug you see flying around. They mate, lay eggs and then die. So the June Bug is there all year round, just not in beetle form.
Similarly, what attracts June bugs? Even though the June Bug is nocturnal, it is attracted to bright lights. They will gather around security lights, well-lit windows and porch lights. This over exposure to light is believed to sometimes kill the June Bug and they are very often found lying dead the next day under lights and brightly lit windows.
Also know, what is the purpose of June bugs?
June beetle larvae, called white grubs, are about 25 mm (1 inch) long and live in the soil. They can destroy crops (e.g., corn [maize], small grains, potatoes, and strawberries), and they can kill lawns and pastures by severing grasses from their roots.

How long is June bug season?
June beetles live a very short time. After they emerge from the soil in late May and June, the adult beetles live for only a couple of months.
