Description
edit
The larvae are normally orange or red with six legs, but develop eight legs by nymph stage. The larvae are up to 0.2 mm (0.01 in) in size, with adult mites about 1 mm (0.04 in) long.
Life cycle
editThe eggs are laid in damp soil. After hatching, the larvae climb blades of grass and wait for a potential host.[2] With their "blade-like chelicerae",[2] they attach themselves to the hosts and feed on their tissues. After sucking, which lasts several days,[2] they fall off and develop over three stages of nymph to adult mites.
