FIGURE 3: (a) – Mites frozen in situ allow investigators to ob- serve structures in their natural positions. Acaropsis woodi, shown here in a cross-sectioned honeybee (Apis mellifera) tra- chea, was not known to position itself using its setae. Larger individuals are able to occupy larger diameter tracheae, but not able to accompany smaller individuals in smaller diameter tracheae. (b) – Frozen mites allow investigators to capture behaviors as they were occurring, such as feeding from a leaf. (c) – Leptus (Erythraeidae) larva foretarsus clinging to scales of a bristletail host. (a) mounted by R. Ochoa and J. Pettis, (b) and (c) by R. Ochoa; (a) and (b) imaged by E. Erbe, (c) by G. Bauchan; USDA ARS.
