ly influenced by day length, temperature, and precipitation." While "the relative influence of these factors is not well understood," it is known as the frogs generally breed following rainfall, and males call more frequently as temperature and day length increase. Some evidence demonstrates the length of the breeding season length is correlated with latitude, with season length decreasing as latitude increases due to temperature limitations.
Males use a distinct advertisement call, "noticeably different than [sic] release or warning calls," to attract mates. Once a mate has been attracted, the pair begins amplexus, in which "the male tightly grasps onto the female to bring their cloacal openings close together for fertilization." Males are polygynous, generally seeking to mate with as many females as they can attract.
American green tree frogs are insectivores, usually consuming flies, mosquitoes, and other small insects such as crickets. One study suggested the frog selects prey not by its size, but according to its activity level, with the most active prey being the most frequently eaten. The same study showed "nearly 90% of Hyla cinerea prey were actively pursued," with the other 10% being "insects walking or close enough to be snatched up by the frog's tongue."
As pets 
The frogs are popular pets because of their small size, appearance, and the undemanding conditions needed to take care of them. Unlike many amphibians, they do not require artificial heating. They need a large (at least ten-gallon) terrarium and do best with a substrate that will hold some humidity, such as commercial shredded bark or coconut husk bedding, or untreated topsoil on the floor of their terrarium. Tree frogs are arboreal, so the height on the tank is more important than the length. A variety of things for climbing, such as plants or branches, should be in the habitat. A shallow water dish should be included.  Captive frogs should not be handled any more than necessary; when necessary, clean gloves should be worn.
