Scorpionflies

MECOPTERA: SCORPIONFLIES


Definition

- Head extended downwards as a beak with biting jaws.

- Two pairs of similar wings, or wingless.

- The male has the end of the abdomen resembling that of a scorpion (but not able to sting).

- Complete life cycle: egg, larva, pupa and adult.

How & where they live

- Predators of small invertebrates as both larvae and adult.

- Scorpionflies are widespread and conspicuous in the summer, especially along hedges and woodland margins. However, the Snow flea, which is only 3 mm long and flightless, is active in the winter.

Number of species

- In Britain 4 species (3 scorpionflies and 1 Snow flea).

- Worldwide 500 known species.

It's amazing Male scorpionflies have a bulbous and dangerous-looking sting at the end of their very mobile tail (actually the genitalia); if picked-up the scorpionfly will pretend to sting you or a potential predator - very off-putting!
