Figure 7

Morphological changes other than compound eyes during F−0 larval instar. The number on each photo indicates the number of days after ecdysis or starting photographing. All scale bars show 0.5 mm. Species and family names are indicated at the bottom. Developmental stage is shown on the upper right of each photo. (A, B) Dorsal views of the heads. White arrowheads indicate specific pigmentation that appeared during stage 2. (C–J) Magnified views of wing sheaths. White arrowheads indicate wrinkles in the wing sheaths. (C, F) The first day of stage 2. (D, G) The day on which the wrinkles on the wing sheaths appeared. (E, H) The first day of stage 3. (K–L) Magnified views of right foreleg. White arrowheads indicate melanized bristles. Adult emergence was observed on Day 37. (M-b) Ventral views of the heads. White arrowheads indicate the degraded larval labia. (Q) The first day of stage 1. (M, O, R). The first day of stage 2. (T, W, Z) Two days before the onset of stage 3. (U, X, a) One day before the onset of stage 3. (Y, b) The first day of stage 3. (N, P, V) The last day of stage 3. (c) Schematic diagrams on the timing of the morphological changes during F−0 larval instar.
