Pale Morning Dun
A small pale yellowish mayfly that hatches in large numbers on western North American streams during late spring. It is a crucial food source for trout.
Did You Know?
Pale morning duns often hatch in such dense swarms that trout become highly selective, ignoring all but perfect imitations.
Golden-Ringed Dragonfly
The longest dragonfly in Britain, adorned with bold black and yellow rings along its body. Females have a conspicuous ovipositor used to inject eggs into stream beds.
Did You Know?
The larvae of golden-ringed dragonflies live buried in stream sediment for up to five years before emerging as adults, ambushing prey from their sandy hideouts.
