The mode of attachment of mite larvae (Leptusspp.) to harvestmen (Opiliones)

Larval mites of the Leptus group (Family Erythraeidae), ectoparasitic on adult harvestmen, deposit at the attachment site a cementing substance forming a superficial cone that concurrently with the distension of the distal portions of the inserted chelicerae promotes firm anchorage in order to ensure the long attachment of the larvae to the host.
