Greek: derma = skin, centeo = biting; Latin: reticulum = small net (English = ornate cow tick).
Formerly it was thought that D. marginatus (Sheep tick) is identical with D. reticulatus.
This 3‐host tick (Fig. 1) is characteristic for southern Europe, but now enlarges its biotopes considerably northward; e.g., it is found in almost all German regions (perhaps a reaction to global warming). Larvae and nymphs feed on rodents, mice, rabbits, and birds, while adult stages attack larger animals (e.g., cattle, deer, horse, dogs) and humans. This species involves, obligatorily, 3 hosts in its life cycle, while other Dermacentor spp. (e.g., D. albopictus, D. venustus = Anocentor = D. nitens) may be 1‐host ticks which molt on their hosts. The development of D. reticulatusin the egg takes 14–21 days, sucking as larva needs 2–6 days and molting takes 14 days on the ground to develop into the nymph. The nymphs feed for about 5 days on a new host and after dropping down to...
