Coniopteryginae (2 in Semidalis and 2 in Conwentzia) to mate in the 
staggered parallel position similar to that reported by Collyer. 
Eggs are laid singly on vegetation, frequently along leaf margins 
(Withycombe 1923) or on the underside of leaves near the midrib 
(Quayle 1912). Muma found S. vicina to produce 2-5 eggs daily for 
16-25 days for a maximum of 266 eggs per female. 
Adult longevity varies with environmental conditions. Muma 
(1967) found S. vicina adults to live about one month. 
The Coniopterygidae are divided into 2 subfamilies: 
Key to subfamilies 
One radio-media cross-vein in middle of fore wing. 
Galea one-segmented. No plicaturae on abdomen. 
.Coniopteryginae 
Apparently two radio-medial cross-veins in middle of fore wing 
(either actually two radio-medial cross veins or one and Mi+ 2 and 
R4+5 briefly coalesce with the part of R4+5 between the point of 
fusion and the stem of Rs appearing as a second cross-vein). Galea 
three-segmented. Plicaturae present on abdomen . 
. Aleuropteryginae 
Subfamily Aleuropteryginae Enderlein, 1905 
Aleuropteryginae Enderlein, 1905:225. Type: Aleuropteryx Low. 
Head capsule dorso-ventrally elongated in lateral view, genae 
long. Galea with basigalea and terminal knob. 
Fore wing with 2 radio-medial cross-veins and possible basal 
cross-vein. M has 2 setae in middle of wing, the bases of which are 
enlarged (except Bidesmida and possibly 2 other genera pot in the 
area of this study). M frequently narrowed between setae. In hind 
wing, M and Cui run close to each other for more than half the 
length of Cui; frequently without any membrane showing between 
them. Rs branches off from R near base of wing. Radio-medial 
cross-vein strikes stem of Rs basally of radial cross-vein and strikes 
M (when M is forked) on the anterior branch. 
Plicaturae present on sterna 3-6. Wax glands of abdomen in a 
narrow transverse band on each of first eight terga (except one 
genus not in area of present study) and surrounding plicaturae. 
Eighth segment normally with stigmata. Ninth segment of males 
strongly sclerotized.
