Summer is a great time for insects to reproduce. Insect populations for the summer can reach the trillions. Some insects hatch their larvae in the bark and needles of trees. These larvae are at risk for birds to eat them. Other insects lay their eggs in water where their larvae can hatch and mature, however fish are their main predator. Birds are also known to dive into the water for a refreshing snack. During the fall and winter months as the weather gets colder, insects burrow into trees or crawl deep underground where they go into a dormant state.
