Frogs

Frogs are amphibians, dependant on water in which to lay their eggs. Most frogs live near or in water but some species, such as the wood frog and tree frog, will venture a distance from water during the summer. The frog species encountered around the home landscape are the American green frog, gray tree frog, wood frog, leopard frog, pickerel frog and bull frog (see above photo). All frogs are harmless to people, pets and plants. They all are beneficial because of the insects that they consume.

Young frogs will often migrate from the body of water where they were born. Many people find the mass migration of young frogs to their backyard ponds very interesting. These migrations only last a few days. The mating season for frogs is March through June. Their chorus of croaking is a pleasant sound of spring and summer. Their jell-like eggs are laid in the water and hatch into tadpoles in about ten days. Bull frogs can grow to almost 6 inches long (sitting position). They will occasionally eat small goldfish. An unwelcome bullfrog can be caught at night using a net and a flashlight. It can be released into another pond or swamp.
