Symphylan Checklist

Symphyla of Britain and Ireland

Somewhat resembling miniature whitish centipedes, symphylans are typically up to about 8 mm long and can often be seen running rapidly over the soil surface when stones are turned over. They occur in all sorts of soils and can be present in large numbers (up to 80 million per acre in one estimate). They can sometimes become a serious greenhouse or outdoor pest attacking the roots of young plants.
 
Antennae are prominent, with 5-60 segments and very flexible; eyes are absent. There are 12 leg pairs but the first pair is often much reduced and not visible. The rear end bears a pair of prominent conical cerci with setae.
