Behaviour

Green treefrogs spend the day hidden in vegetation and come out at night to hunt insects, often around porch lights. Males call in loud choruses from plants at the water's edge on warm, humid nights.

Why they matter

They eat mosquitoes and other insects in great numbers and are food for snakes, birds and fish. Their thin skin makes them sensitive to pollution, so a chorus of green treefrogs is a sign of healthy wetlands nearby.

Reproduction and lifecycle

Eggs — Several hundred, laid in small clusters on floating plants
Hatching — In a few days
Tadpoles — Change into frogs in about 5 to 8 weeks
Maturity — In their first year
Lifespan — A few years
Calling — Males call through the warm months

Living around people

  • A treefrog on a window is hunting insects; it is harmless.
  • Pesticides and lawn chemicals harm frogs; a garden pond without fish helps them breed.

Misconceptions

  • Treefrogs cause warts. No frog or toad causes warts.
  • Frogs calling means rain is coming. They call in humid weather, which often comes before rain, but they call for mates.
