I found this insect, in multiple zones of Imbabura - Ecuador. https://en.wikipedia.org/wiki/Imbabura_Province

Sorry for not having something to scale with, but it's about 15 cm long.

Mosca de pescar oriental macho. Male dobonsfly.

Another picture here: Mosca de pescar oriental hembra. Female dobonsfly.

  • $\begingroup$ In general, it helps identification if you add the location where on earth you found the animal. $\endgroup$ – Arsak Feb 18 '18 at 16:13

That is a male dobsonfly. I know this is a male because it has long mandibles which are used in mating. Female dobsonflies have short mandibles. larval dobsonflies are called hellgramites,and it really hurts a lot when they bite you.Look here https://en.wikipedia.org/wiki/Dobsonfly or here entnemdept.ufl.edu/creatures/misc/eastern_dobsonfly.htm

  • $\begingroup$ Yes, Megaloptera, Corydalidae, Corydalus cornutus $\endgroup$ – Karl Kjer Feb 18 '18 at 16:21
  • $\begingroup$ Just in case, does anyone know its name in Spanish? $\endgroup$ – Joshua Salazar Feb 19 '18 at 3:57
  • $\begingroup$ I edited the question @peter . So I should suppose that the second photograph is a female, right? $\endgroup$ – Joshua Salazar Feb 19 '18 at 3:59
  • $\begingroup$ I found the Spanish name. A dobonsfly is a "Mosca de pescar oriental" $\endgroup$ – Joshua Salazar Feb 19 '18 at 4:06
  • $\begingroup$ I didn't see the second picture. when I saw the first picture, I thought "I know what that is!" and just jumped at it. The second picture is a female, the long mandibles of the male are used in mating. $\endgroup$ – peter Feb 25 '18 at 20:21

Not Corydalus cornutus. That species is only found in Eastern North America. There are several other Corydalus species found in that part of South America. It would require an expert in them to get a more specific ID. Note that the pictures are of two different insects as well. The one on top is a male, the bottom one a female (as the earlier answer noted, females have shorter, more robust and powerful mandibles, though males and females can each draw blood with a nip (personal experience)).
