Red velvet mites

Erythraeidae Balaustium sp.
Trombidiidae Allothrombium sp.
Anystidae Anystis baccarum (L.)

Acari:Erythraeidae, Trombidiidae, Anystidae

Balaustium is a large, bright red mite with a tick-like shape and a dense velvet-like covering of dorsal setae; chelicerae are long and retractable (A). Moves very quickly over the plant surface. Allothrombium is also a bright red mite, but with few hairs and non-retractable chelicerae (B). Anystis is a small red mite that can be found moving rapidly along the foliage (C).

Note: Sensitivity of these species to insecticides is not well known.


Balaustium is an important predator of mites, scales, and moth eggs at the beginning and end of the season. Allothrombium feeds on aphids and mites. Anystis hatches from eggs in soil litter during early spring; it feeds on leafhoppers and phytophagous mites. Prey searching occurs along apple leaf veins and edges. They may eat up to 40 adult twospotted mites per day.
