Also called helicopter damselflies, these have very long abdomens. In addition to having a pterostigma on the front edge of the wing, like other damselflies, a marking extends over several wing cells and may differ on the fore- and hindwings.

in water collected in the leaves of epiphytic plants. In some species, males guard the egg-laying sites.

Biddies

I liese large dragonflies are brownish or black with yellow markings. The eyes touch each other at a single point. Most members of this family have a long abdomen.

Females lay their eggs at the bottom of fast-flowing streams and rivers. The nymphs live buried in the mud or gravel, with just the head and front legs exposed to seize passing prey. Nymphs may take up to five years to mature, and many species live for only a few weeks as adults.

• OCCURRENCE Northern Hemisphere. Along mountain or woodland streams; sometimes over open ground near pools.

• Life Cycle After mating, the female skimmer flies above the water and dips her abdomen down to release a few eggs into the water. Just one female can lay more than 2,000 eggs. The nymphs usually develop in bodies of stagnant water, such as marshes and peat bogs, and hunt for prey along the bottom.

• Occurrence

Worldwide. Gommon around stagnant water; sometimes found near streams.

Clijb-tailkd dragonflies

I he common name of these relatively large dragonflies refers to the unusually shaped abdomen of the males - and often of the females. The abdomen is swollen just in front of its apex, giving it the appearance of a club. (Mub-tailed dragonflies have widely separated eyes, and most species are brightly colored in differing combinations of black, yellow, or green.

• I II I CYCLE Mating takes place among vegetation. Eggs are laid in shallow water, with the female lashing the surface with the end of the abdomen in order to release the eggs. The nymphs are bottom-living, crawling and burrowing to catch their prey.

• OCCURRENCE Worldwide. In ponds, lakes, rivers, and streams.
