The female chooses the male based on his call and breeding occurs between April and August.
According to A Guide to the Frogs and Toads of Virginia published by the Virginia Department of Game and Inland Fisheries (and which each ORMN is issued at the beginning of the training course), the Gray Treefrog is 1.25-2.4 inches in length and typically has a dark star-shaped pattern and many minute warts on a gray to light green background. However, it can also be almost solid color with very subtle markings in order to blend in to their environment.They have a light spot beneath the eye and the inner thighs are orange or yellow.
The Gray Treefrog lives through the winter by producing a type of antifreeze from glycol in the cells. The glycol turns into glucose which keeps the frog from freezing. Its breathing and heartbeat then stop until the temperature warms up again.
Harvesting garden potatoes has slowed to an archaeological pace in order to protect the small Eastern Spadefoot (Scaphiopus holbrookii) frog. The only tool which can safely be used is a small trowel but the safest technique is to slowly move the soil aside by hand and wait to hear the startled squeak when the frogs are uncovered. They are named for the tiny dark spade on their back feet which they use to move soil aside and create cool burrows underground. These little frogs (1.75-3 inches long) are explosive breeders and usually remain buried, only emerging from their burrows after heavy rains to breed. During periods of extensive drought, they encapsulate themselves in an underground mud chamber to prevent moisture loss.
It is worth the extra time it takes to dig the potatoes in exchange for the insect-control benefits the Spadefoot offers.
Difference between frogs and toads:
- Live near water in order to reproduce
- Have a narrow body
- Have smooth, moist skin
- Have higher, rounder, bulgier eyes
- Take long high jumps with longer hind legs
- Have many predators
- Do not need to live near water to survive
- Have a wider body
- Have rough, dry, bumpy skin
- Have lower, football shaped eyes
- Have shorter, less powerful hind legs
- Will run or take small hops rather than jump
- Do not have many predators as their skin lets out a bitter taste & smell
