  Megaloptera - Facts, Information, and Encyclopedia Reference article
Megaloptera, from the Greek words mega, meaning large, and ptera, meaning wing, is an order of insects containing alderflies, dobsonflies and fishflies.
Members of Megaloptera undergo complete metamorphosis, and their aquatic larvae dwell in fresh water, around which the adults also live.
The most well-known of the Megaloptera is probably the dobsonfly, which have tusk-like mandibles - the males especially are formidable in appearance yet are relatively harmless to humans.

 Megaloptera
Megaloptera adults lay their egg masses on rocks, tree trunks, leaves, and other substrates adjacent to water, and the young larvae fall or crawl into the water shortly after hatching.

 SETAC 2005   (Site not responding. Last check: 2007-10-12)
Megaloptera larvae are in contact with sediment for two to five years, have high lipid content, and are opportunistic feeders.
Residues of total TEQ in Megaloptera were generally an order of magnitude greater at target sites (15.9 to 36.3 ng/kg) than at reference sites (0.61 to 4.5 ng/kg).
Thus, it would appear that Megaloptera species may be useful for screening level dietary exposure assessments as a site-specific worst case benthic invertebrate.

 God of Insects - Museum: Megaloptera
Megaloptera is the order that contains the dobsonflies, fishflies and alderflies.
Some scientists consider them a suborder of the Neuroptera but we will treat them as a separate order.
Large wings characterize these insects, a trait which earned them the ordinal name "Megaloptera", derived (with no surprise) from the Greek words for “large-wing”.

They are familiar to professional and amateur entomophiles alike because of their morphology and biology, with many families often prized as curiosities by collectors.
Neuroptera, along with the smaller orders, Raphidioptera and Megaloptera, are among the oldest Holometabola, many exhibiting a variety of primitive characteristics (Hennig 1981, New 1989, Kristensen 1999).
This was questioned by Boudreaux (1979), who instead suggested that Raphidioptera were sister to Megaloptera+ Neuroptera; a view recently supported in a cladistic analysis of morphological characters by Aspöck et al.

 Megaloptera spit out from Neuroptera? - BugGuide.Net
Talk to an aquatic entomologist, and they all say Megaloptera (the aquatic neuroptera) are elevated to order.
As I said, I like the suborder idea, because there are already so many orders, and the Neuroptera are a well-known, traditional groupage of related families.
The use of suborders seems to maintain the relationships represnted by having orders for Megaloptera and the others.

A preliminary survey of the Megaloptera of Oklahoma showed the presence of the species each of Sialidae (alderflies) and Corydalidae (dobsonflies and fishflies).
The Megaloptera is a small group of medium to large species of insects (10-75 mm in length).
Despite being interesting, rather widely distributed, and, at times, locally abundant, the Megaloptera, as a group, have not been well collected in Oklahoma.

 MEGALOPTERA
So far as aquatic insects are concerned, the first Order displaying complete metamorphosis is the Order Megaloptera, comprising in terms of common names, the alderflies, fishflies, and dobsonflies.
Students of insect systematics and phylogeny are not in agreement as to whether these families constitute an Order of their own, the Megaloptera, or whether they should simply be placed in the larger Order, Neuroptera, grouped as a sub—family with either the name Megaloptera or Sialiodea.
By placing the alderflies, dobsonflies, and fishflies in the order Megaloptera, we are left with only a single North American family in the order Neuroptera.

The Order Megaloptera includes the snakeflies which some entomologists consider should be placed into the separate Order Raphidioptera.
Still others are of the opinion that both these Orders should be placed within the Order Neuroptera.
