They jump into the water, and lie motionless in the sludge under water till they feel safe again. They are beautifully marked in shades of green, brown, black and white. They attain a maximum length of 81mm. They usually breed in autumn. Eggs are laid in shallow water and these hatch after about seven days.
Metamorphosis is slow and takes approximately nine months.
When food is in short supply, this period may stretch to two years. They can be heard calling throughout the year in the evening. The Grey Tree Frog is the largest of the South African arboreal frogs. They occur from the Hluhluwe area in Kwazulu-Natal through the Eastern Lowveld to our Northern Bushveld areas. We find them from time to time in the Pretoria area.
