Pupa. Length 20— 28mm. Antennae reaching abdominal segment 7—8 in 

 male pupae, segment 5 in female. Frontal sclerite convex, overhanging 

 labrum but not as markedly as in Ph. grand is. Labrum (Figure 43) 

 and anteclypeus uniformly wide, concave laterally; anterior margin 

 with indistinct, blunt, rounded process with a small thin seta on each side; 

 5 dark long setae at some distance; median seta of anteclypeus long, 

 outer seta short, intermediate seta of medium length. Mandibles 

 (Figure 44) sickle -shaped, with rugose surface on curvature; basal setae 

 short, situated on a small tubercle. 



Dorsal process of abdominal segment 1 with sharp, angular processes 

 on each side of apex (Figure 45). Lateral line with black setae, small 

 and sparse on segment 3, dense and large further posteriorly, especially 

 on segments 6 and 7, reaching ventral side on segment 8. Segment 1 without 

 gills; gills of segments 2—8 as in the larva. Usual number of spinules 

 on holding apparatus: 111:0-1; lV:3-4; V:6-7+ 11-21; VI:7-8; V1I:8-11; 

 VIll:2-5. 



Anal appendages with 4 short, thin setae near posterior margin. 



Case attached among vegetation, anterior and posterior ends covered by 

 tangled stalks and pieces of plants; tube with sievelike anterior and 

 posterior closing membrane inside. 



Mode of life and habitats. Stagnant and slowly running waters, 

 in the vegetation zone, among plants and on the bottom. 



Distribution. USSR: European part, Siberia, western part of Amur 

 Region. In addition, Central and Northern Europe, Mongolia.

Full-grown larva. Length 30— 40 mm (Figure 46). Resembling 

 Ph. bipunctata in form of body pattern and chaetotaxy, differing in 

 minor structural details and coloration. 



Head light yellow, with narrow, distinct reddish brown stripes. Median 

 stripe of frontoclypeus not narrower anteriorly as in Ph. bipunctata, 

 but wider than dorsal stripes and less dark. As in Ph. bipunctata, 

 a large, bright spot at eye level near seta 9 on the dark dorsal stripes. 

 A small spot behind the large spot. Seta 11 thin, light, situated near the 

 small spot; setae 14 and 15 situated lateral to dorsal stripe, close to its 

 margin in bright indentations; seta 17 thin, long, on light dot in posterior 

 part of stripe. Lateral and dorsal stripes distinct. Sclerites on ventral 

 side with dark margin lateral to gula and at margin of occipital foramen; 

 groups of reddish brown dots, sometimes indistinct, in each half.
