Protohermes Maculiferus
''Protohermes'' is a genus of dobsonflies in the family Corydalidae. ''Protohermes'' is the most speciose 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 genitalia are diverse across the genus and can be useful only 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 of large p ...

Nocturnality
Nocturnality is a behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including humans (except for ni ...
