Nymph of a golden stonefly, Plecoptera, Perlidae Dinotoperla imago (adult) (Gripopterygidae: Dinotoperlinae) Stoneflies have a generalized anatomy, with few specialized features compared to other insects. They have simple mouthparts with chewing mandibles, long, multiple-segmented antennae, large compound eyes, and two or three ocelli. The legs ...
However, as they mature, they typically become carnivores consuming chironomid midge, mayfly, caddisfly, and stonefly larvae. [6] The mouths of carnivorous nymphs are usually for grasping and penetrating prey; however, mouths of herbivores are used for scraping and grinding. [7]
Carnivorous stonefly, caddisfly, alderfly and dragonfly larvae feed on bottom-dwelling mayfly nymphs, as do aquatic beetles, leeches, crayfish and amphibians. [27] Besides the direct mortality caused by these predators, the behaviour of their potential prey is also affected, with the nymphs' growth rate being slowed by the need to hide rather ...
Acroneuria lycorias or the boreal stonefly is a species of stonefly native to North America. It was first described by Edward Newman in 1839. The species is named after the Nereid Lycorias of Greek mythology .
As with most stonefly E. spectabilis is a completely aquatic carnivore at juvenile stages, developing into a less voracious winged, ephemeral adult.. Laying and egg shape of many stoneflies including E. spectabilis was largely researched by Hugh Bernard Noel Hynes, [3] where eggs enter the stream by deposition via the females ovipositor.
The Capniidae, the small winter stoneflies, are a family of insects in the stonefly order (Plecoptera). It constitutes one of the largest stonefly families, containing some 300 species distributed throughout the holarctic. Their closest relatives are the rolled-winged stoneflies . [1] [2]
Eustheniidae is a family of insects in the order Plecoptera, the stoneflies.They are native to Australia, New Zealand, and Chile. [1]The nymphs live in lakes and in swift-flowing rivers and streams, where they cling to rocks.
The family Perlodidae is composed of at least 50 genera and over 350 species, with the fossil records extending at least from the Triassic. The majority of perlodid stoneflies are univoltine - one generation occurs per year.
