''Protohermes'' is a
genus of
dobsonflies in the family
Corydalidae.
''Protohermes'' is the most specious and widely distributed genus within
Megaloptera
Megaloptera is an order of insects. It contains the alderflies, dobsonflies and fishflies, and there are about 300 known species.
The order's name comes from Ancient Greek, from ''mega-'' (μέγα-) "large" + ''pteryx'' (πτέρυξ) "wing ...
, 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
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation).

of larvae is closely tied to the availability of different sizes of prey.
Dwarfism
Dwarfism is a condition wherein an organism is exceptionally small, and mostly occurs in the animal kingdom. In humans, it is sometimes defined as an adult height of less than , regardless of sex; the average adult height among people with dw ...
occurs in populations on islands and peninsulas as a result of fewer species of large prey, and
maturation
Maturation is the process of becoming mature; the emergence of individual and behavioral characteristics through growth processes over time.

may be synchronous with prey in locations with
seasonal variability. Larger larvae do not consume smaller prey, and they actively
select prey as an
ambush predator. Larvae are motionless 90% of the time during the day, but do change position on the stream bed
during the night.
