| Arctic species of mayflies, scale insects, midges, caddisflies and other groups are known to be parthenogenetic. |
| The Permian saw the appearance of stoneflies, true bugs, beetles, and caddisflies, among other groups. |
| Differences were especially large for gastropods, leeches, caddisflies, mayflies, and chironomids. |
| Young Atlantic salmon in streams eat mainly the larvae of aquatic insects such as blackflies, stoneflies, caddisflies, and chironomids. |
| No baetid mayflies were recovered in pools after the spate and only a few hydropsychid caddisflies were observed in this habitat throughout the study. |
| They hope to see up to 100 different moth species, plus many beetles and caddisflies. |
