WHAT ARE NYMPHS?
Strictly speaking, nymphs are the immature stage of upwinged flies or damselflies that develop on the lakebed before swimming to the surface, or in the case of damselflies, to the shore, before emerging into a winged adult form. Other species like buzzers (chironomids) or sedges don’t technically have a nymphal stage and instead are referred to as ‘pupa’. Things become more complicated when we consider the larvae stage of sedges (cased caddis) and the alder larva. If that’s not enough, bolted on are the likes of truly aquatic creatures like corixa, freshwater shrimps and hoglice! Thankfully, as anglers, the whole lot can be bundled together under the generic heading of ‘nymphs’. With that, nymphing can be applied to a whole host of insects and bugs we aim to imitate beneath the waves.
