Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
American green tree frogs are insectivores, primarily consuming flies, mosquitoes, grasshoppers, cockroaches, spiders, beetles, and other small insects such as crickets and ants. [16] One study suggested frogs select prey not by their size, but according to their activity levels, with the most active prey being the most frequently eaten.
The diet of the green tree frog consists mainly of insects such as moths, cockroaches, and locusts. They also eat spiders and can include smaller frogs and even small mammals (including bats [18]) among their prey. [8] [10] Frog teeth are not suited to cutting up prey, so the food item must be small enough to fit inside its mouth.
Despite its classification and climbing abilities, it does not live in trees and spends almost all of its time close to ground level. It can reach up to 11 cm (4.5 in) in length, making it one of Australia's largest frogs. Coloured gold and green, the frogs are voracious eaters of insects, but will also eat larger prey, such as worms and mice.
Lithobates sphenocephalus [1] [3] or Rana sphenocephala, [4] [5] [6] commonly known as the southern leopard frog, is a medium-sized anuran in the family Ranidae (the true frogs). The southern leopard frog is one of the 36 species currently or formerly classified in the Rana genus found in North America. [ 7 ]
Most species (e.g. Blyth's river frog L. blythii or the fanged river frog L. macrodon) develop normally, with free-swimming tadpoles that eat food. [5] The tadpoles of the corrugated frog ( L. laticeps ) are free-swimming but endotrophic, meaning they do not eat but live on stored yolk until metamorphosis into frogs. [ 5 ]
The frogs tend to be less active during the winters and more active during the mating season. For years when there is heavy snow at high elevations, they may only be active for 90 days in the summer. [7] Hibernation tends to happen underwater or in the crevices of stream banks. This occurs during the cold months of winter.
These arthropods are cockroach larvae, dragonfly larvae, and crab spiders. This suggests that the bromeliads not only provide cover during the day, but also a food source. [ 6 ] Sand has also been found in the digestive tract, meaning that the frog forages on the ground.
