Cnemacantha muscaria (Fallén 1823) View in CoL
The living larvae with marked crevices, white, dull due to hairy integument, the Malpighian tubules extended. Egg ( Figs 1, 2 View FIGURES 1 – 8 ). Length 0.61–0.65 mm. Ridges well developed; ribs slightly indicated; Chorion smooth in close view but often perforated; posterior tubercle with well developed perforation.
First instar ( Figs 33, 34 View FIGURES 33 – 38 ). Length 1.04–1.64 mm. Facial mask moderate, (25 scraping cirri per row); the second row of scraping cirri medially shortened. The peristomal cirri filamentous. The ventral organ lobe-like, with two digitiform processes.
Cephaloskeleton ( Fig. 162 View FIGURES 162 – 167 ). Length 0.36– 0.27 mm. Mouth hooks with 4–5 apical teeth, the teeth more or les directed laterally; stalked part hyaline.
Second instar ( Figs 35, 36 View FIGURES 33 – 38 ). Length 1.57–2.23 mm. Facial mask narrow, up to 10 scraping cirri per row; the scraping cirri in first row very short. The peristomal cirri of two types. Thoracic segments with comb spines anterodorsally. Abdominal segments and anal division covered by stout spines. Anterior spiracles simple, oval.
Cephaloskeleton ( Fig. 177 View FIGURES 177 – 182 ). Length 0.42–0.45 mm. Mouth hooks robust, strongly converging, ending in 3 robust teeth; dental sclerite massive. Intermediate sclerite strong. Epistomal sclerite semilunar from dorsal view, posterior hyaline plate with two corners at posterior margin. Subhypostomal sclerites stalked, subparallel, anterior tips opposite. Dorsal bridge trapezoid, as long as wide. Dorsal and ventral cornua roughly equal; posterior third of ventral cornua hyaline. Cibarium hyaline.
Third instar ( Figs 37, 38 View FIGURES 33 – 38 ). Length 2.23–3.15 mm. The facial mask as in second instar. First thoracic segment dorsally and laterally with comb spines; second and third ones with comb spines all around anterior border. Body segments evenly covered by stout spines. Anterior spiracles with 4 papillae.
Cephaloskeleton ( Fig. 192 View FIGURES 192 – 197 ). Length 0.68–0.78 mm. Mouth hooks strong, converging. Intermediates sclerite short, straight from lateral view, tips arched and converging; ventral bridge narrow and arched from ventral view. Epistomal sclerite shorter than broad, posterior hyaline plate with two corners. Subhypostomal sclerites stalked, converging. Dorsal bridge semilunar. Ventral cornua posteriad weakly sclerotised. Cibarium hyaline.
