Term for Damselflies, Mayflies etc.

[Clanky]

What is the technical term to describe insects, such as damselflies, mayflies etc. which lay their eggs in water, whose larval forms live in water and which emerge to metamorphose into their adult form?
Many thanks in anticipation. Pete

Dragonflies, damsel flies and mayflies belong to a group known as Paleoptera. However this is 'ancient winged insects' so doesnt help a lot. Best teminology I can come up with is 'aquatic insect' - not terribly exciting but it refers to an insect that spends part or all of its life cycle in water- includes springtails, water beetles etc as well as the Paleoptera

To those of you who tried to help, thanks. My question wasn't entirely clear. I wasn't after the names of particular species, rather the single adjective that describes all insect species whose aquatic larval forms change into above-water adults [rather like andromous describes all fish species that spend most of their lives at sea but return to freshwater to spawn e.g. salmon]. I'm sure I've seen such a word but, despite trawling around many sites about insect swith such life cycles, I can't find it anywhere. Maybe I've imagined it - but thanks anyway. Pete
