What are symphylids?

Symphylids are small white arthropods which move through soil pores and feed on root hairs and small roots. Adults can reach 5 mm in length and have 12 legs and 2 antennae. The life cycle can take 3 months to complete, but adults can live longer. The extent of their damage is currently been researched, but may cause direct damage when present in large numbers. Secondary infections from fungi can compound symphylid damage.

How can I spot them?
