Chlaenius circumscriptus preying upon a tree frog, Hyla savignyi. Epomis is a subgenus of ground beetle genus Chlaenius. The larvae of this subgenus are notable for being obligate role-reversal predators. [1] Amphibians such as frogs are normally predators of beetles; however, Epomis larvae feed exclusively on amphibians. [2] [3]
S. buqueti can reach a length of 25–50 mm (0.98–1.97 in). [1] These iridescent, colorful beetles have a striking sexual dimorphism. The males are much larger and have very long and strong hind legs (hence the common name frog beetle).
Beetles of this subfamily are also known as "frog-legged beetles" or "kangaroo beetles". They are very distinctive due to their metafemora, or third pair of legs, which are distinctly larger than other femora and generally sport some type of ridge or tooth on the ventral side.
Sagra is a genus of beetles belonging to the family Chrysomelidae, commonly referred to as frog-legged beetles or kangaroo beetles. List of subgenera and species
The larvae can often evade the first strike of the amphibian by being alert, and then strike back at once, while the amphibian is in close proximity. Latching on with their mandibles, they suck the body fluids of their new host, progressing to chewing its skin and eating its tissues. Eventually they may kill their host.
Green June beetles are commonly seen flying near the ground in landscapes in the summer. Native plant-eating beetles should soon make an appearance in Georgia Skip to main content
Frogs are apparently not affected by Meloidae beetle toxin, and "consume meloids with impunity". [6] After eating blister beetles, frogs retain the toxin in their tissues and secrete it in their mucus for a short time, and predators that consume the frogs can be poisoned. This includes humans who consume foods such as frog legs.
These families are best known for the nymphal stage, which produces a cover of foamed-up plant sap visually resembling saliva; the nymphs are therefore commonly known as spittlebugs and their foam as cuckoo spit, frog spit, or snake spit. This characteristic spittle production is associated with the unusual trait of xylem feeding.
