Order Megaloptera has two families and sixty genera. All alderflies, dobsonflies, and fishflies have aquatic larvae. The adult alderflies are diurnal. The adult dobsonflies and fishflies are nocturnal. They all have large wings and the hind wings are pleated to aid folding. They have compound eyes and chewing mandibles. Megaloptera undergo complete metamorphosis. Males use vibrations or scent glands to attract a mate. The females lay their eggs on rocks or leaves near water. They have predaceous larvae that capture other aquatic insects. They become scavengers when kept in captivity. The larvae take several years to reach maturity. Once they are mature, they create a chamber where they take several days to molt and pupate. The adults have a lifespan ranging from a few hours to a few days. Their primary concern is reproduction and most species do not feed, but will sometimes drink water. Megaloptera have been around since the Permian.
There is one other problem. I think that your article is a little random, as if you decided to take all the facts and throw them randomly into the article. I suggest you organize your article in paragraphs, each paragraph talking about something separate.
This article is very informative and well-written. However, there are a few problems with the article. Firstly, Wikipedia is not a valid reference. Although I personally agree that Wikipedia should be considered a valid reference, the overwhelming majority of the scientific community disagrees with my point of view. I am sure, however, that there are plenty of good, valid, and informative references in the Wikipedia article itself.
