Protohermes Basiflavus
''Protohermes'' is a genus of dobsonflies in the family Corydalidae. ''Protohermes'' is the most specious and widely distributed genus within Megaloptera, but up to 85% of species are restricted to small endemic areas in Asia. This endemism may be a result of an association with high elevation and high slope streams in Northern Vietnam and China. Description Adult ''Protohermes'' generally have yellow coloration with white spots on the wings. The male genetalia region is diverse across the genus and can be useful for species-level identification, especially the shape and size of the tenth tergum and the subgenital plate at the ninth sternum. Nuptial gifts in ''Protohermes'' may as large as 20% of the total body mass of the male and can require up to 2 days to recover before mating again. The size and phenology of larvae is closely tied to the availability of different sizes of prey. Dwarfism occurs in populations on islands and peninsulas as a result of fewer species ...

Ambush Predator
Ambush predators or sit-and-wait predators are carnivorous animals that capture or trap prey via stealth, luring or by (typically instinctive) strategies utilizing an element of surprise. Unlike pursuit predators, who chase to capture prey using sheer speed or endurance, ambush predators avoid fatigue by staying in concealment, waiting patiently for the prey to get near, before launching a sudden overwhelming attack that quickly incapacitates and captures the prey. The ambush is often opportunistic, and may be set by hiding in a burrow, by camouflage, by aggressive mimicry, or by the use of a trap (e.g. a web). The predator then uses a combination of senses to detect and assess the prey, and to time the strike. Nocturnal ambush predators such as cats and snakes have vertical slit pupils helping them to judge the distance to prey in dim light. Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expandin ...

Protohermes Orientalis
''Protohermes'' is a genus of dobsonflies in the family Corydalidae. ''Protohermes'' is the most specious and widely distributed genus within Megaloptera, but up to 85% of species are restricted to small endemic areas in Asia.
