As mites are very small organisms, working with them is difficult and requires extensive experience and technical skills. Figure 1 shows a larval and a female house dust mite. Adult dust mites grow to be only 0.4 mm in length. Figure 2 shows a larva of the chigger mite with a body size of 0.1 mm.
Fig. 1: Right: Adult house dust mite (Dermatophagoides pteronyssinus) with a body size of 0.4 mm, left: larva.
Fig. 2: A chigger mite (Neotrombicula autumnalis) larva, the only parasitic stage of the species, walking on a blade of grass.
