Summer evenings can be an excellent opportunity to enjoy the outdoors, as long as you are prepared to deal with the heightened activity of insects. Some of these summer insects can be harmful, like mosquitos. Other insects can be considered more of a nuisance than an attacker. One example of the latter is the scarab beetle, commonly known as the June bug. This nighttime aviator is slow, clumsy, and is attracted to lights. Other than the random misfortune of stepping on one, these beetles leave humans alone. On the other hand, these beetles are one of the main sources of grub damage in lawns.
