The larvae of N. sympatrica preferred to stick inside the cochlea (64.39%) and on the edge of the ear (20.69%), while they were found to be present on the chin only in 0.06% of all feeding individuals. 38.80% of mites from all collectings were found in combings. The localisation of feeding larvae of N. sympatrica in various infested regions at the summer-autumn period showed seasonal variations (Fig. 2). In summer the number of stuck mites reached 79.39% in the cochlea, 15.94% in the ano-genital region, and 4.69% in the ventral region. Increasing quantity of mites in the cochlea up to 89.42% was observed in autumn, which accordingly caused a decrease in the amount of larvae in the ano-genital region (9.10%) and in the ventral region (1.48%). The number of larvae of N. sympatrica was higher in autumn (58.0%) than in summer (41.99%). In summer the proportion of the feeding individuals of N. sympatrica (50.63%) and individuals found in combings (49.37%) was nearly identical (Fig. 3). However, in autumn a substantial increase of the feeding larvae (72.14 %) and decrease of larvae found in combings (27.86%) were observed.
