Seaside dragonlet

It is the only dragonfly in the Americas that can breed in seawater.

In a lab test, its babies survived water more than two and a half times saltier than the sea.

Females come in many colours, often bright orange with black stripes.

Pairs fly together and even lay their eggs together, usually into floating mats of seaweed.

In one study in a Maine salt marsh, it spent 99 out of every 100 minutes sitting on plants.
