Recently I posted an article about native treefrogs in my own collection: My Animal Collection: How a Herpetologist Keeps Barking Treefrogs (Hyla gratiosa) and Gray Treefrogs (Hyla versicolor). Today I’d like to add some thoughts on another US native, the very attractive green treefrog. Please see my earlier article for detailed information on treefrog care.The green treefrog is so often collected for the pet trade, and so inexpensive, that many here take it for granted. It is, however, one of the most beautifully colored of the word’s Hylids, and much favored by hobbyists in other countries.
Green treefrogs top out at 2 ½ inches in length, and are slender in build. I’ve found that they do best when given only small insects, the size of a ¼ to ½ inch cricket, despite their willingness to tackle larger prey. I suggest that you avoid adult crickets, large waxworms and the like, as they may be too much for this species’ digestive system to handle on a regular basis.
Perhaps due to their arboreal nature, these frogs react very strongly to flying insects. The feeding response is quite dramatic when I offer them moths and small flies, and noticeably different than their reaction to crickets and waxworms. Small wild-caught insects (Zoo Med’s Bug Napper is an excellent trap) should be given regularly. Most green treefrogs feed readily from plastic tongs….canned silkworms are an excellent addition to the diet. These frogs are persistently arboreal, so burrowing insects such as small butterworms and waxworms should be placed in cups suspended from tree branches, or hand-fed.
Green treefrogs are accomplished jumpers, and adept at snatching insects on the wing. At feeding time, a group I housed in the Bronx Zoo regularly stole the show from their somewhat sedentary exhibit mates – a pair of water moccasins!
Unfortunately, little attention is given to breeding this spectacular frog in captivity. Males in the zoo group I mentioned began calling in response to increased showers, but the females did not respond with eggs. As most green treefrogs in the trade hail from Florida and Louisiana, a dry period followed by frequent misting and a rise in temperature of 5-10 F might do the trick.
