TIL that dragonflies live most of their life underwater as larvae. - Lemmy.ca

>The Larva: It is interesting to note that even though we’ve seen dragonflies mostly flying around us during hot summer months, they spend most of their life underwater as a larva. They can live underwater for as long as two years, and this is considered to be the longest stage in the life cycle of a dragonfly. After hatching, the larva has six tiny legs, hinged jaw and winged sheaths.
