Immature
Stages of Scoliidae
Immature stages of Scoliidae were discussed in detail by Clausen
(1940), as follows: The eggs of the different species of Scoliidae range in length from
ca. 2.0 mm. to the 4.0 mm. of the enormous Scolia oryctophaga
Coq. of Madagascar. They are ca.
1/4th as wide as long, with the anterior end slightly the wider; both poles
are smoothly rounded, the ventral side is almost straight , and the dorsum is
slightly convex. The chorion is not
ornamented, thin, and transparent (Clausen 1940). There is little detailed information on the characters of the
larvae. There are 4 larval instars,
which do not differ in general appearance, although in the instars following
the 1st the anterior segments of the body are long and narrowed. There are no visible integumentary spines
or setae. The mandibles of the 1st
instar are simple, and those of the following instars are tridentated. The mature larva has 10 pairs of
spiracles, located on the last two thoracic and the first eight abdominal
segments (Clausen 1940). References: Please refer to <biology.ref.htm> [Additional
