Dalotia coriaria (formerly Atheta coriaria) is a native species of soil-dwelling rove beetle, which feeds on small insects and mites (e.g., shore flies, fungus gnats, moth flies, springtails, root mealybug crawlers, aphids, spider mites). Both adults and larvae are active, aggressive predators and are attracted to decomposing plant or animal material and algae where their hosts are found.
Dalotia has a longer life cycle and takes longer to establish than the Stratiolaelaps predatory mite, so Dalotia should be used along with Stratiolaelaps for best results.
