Corydalus is a transliteration from the Greek κορδαλος (korúdalos) [3] meaning a crested lark or the flower, larkspur, apparently related to Greek corys (κορυς) a helmet crest. [4] The name probably refers to the long mandibles of the male which might be considered to resemble the crest of a lark, or perhaps, the decorative crests ...
Eastern Dobsonfly (Corydalus cornutus) female. The adult dobsonfly is a large insect up to 140 millimetres long with a wingspan of up to 125 millimetres. [8] The female has short powerful mandibles of a similar size to those of the larva while the mandibles of the male are sickle-shaped and up to 40 millimetres long, half as long as the body. [1]
The eastern dobsonfly, Corydalus cornutus, is the most well-known North American species among the dobsonflies. These genera have distinctive elongated mandibles in males and form the subfamily Corydalinae. The genera in which the males have normal mandibles, called fishflies, form the subfamily Chauliodinae.
The metamorphosis from larva to adult in dobsonflies is one of the simplest of the holometabolous orders, [3] yet the life cycle begins with an intriguing ritualized courtship display (most of the following comes from Simonsen et al. 2008 [8] and all pertains to Corydalus; other courtship rituals remain unknown). Males compete with each other ...
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information.
Corydalus cornutus - MHNT. 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", in reference to the large, clumsy wings of these insects.
Fumarioideae is a subfamily of the family Papaveraceae (the poppy family). It was formerly treated as a separate family, the Fumariaceae (the fumitory, fumewort or bleeding-heart family).
While escaping, the newly hatched larvae of many species sometimes eat the chorion to emerge. Alternatively, the egg shell may have a line of weakness around the cap which gives way allowing the larva to emerge. [61] The egg shell and a small amount of yolk trapped in the amniotic membranes forms the first food for most lepidopteran larvae.
