. As can be seen from these 2 images, the cyclostome mouth is defined by the dorso-ventrally short clypeus and the concave labrum, bordered ventrally by the mandibles.
In some, dorsal carina (ridge)
running down the middle of the first metasomal tergite from anterior end, not always complete to posterior end.
Mummification of host remains. Here
are examples of rogadine mummies.
Occipital carina present
though not always complete at vertex of head.
Worldwide, wherever foliage-feeding Lepidoptera are found. Shaw, SR 1997.(3)
Koinobiont endoparasitoid life cycle (See parasitoid life cycles
Among the cyclostome subfamilies of Braconidae, this, along with the fly parasitoid subfamilies (Alysiinae and Opiinae) seem to be the only endoparasitoids.
By far the most speciose genus in Rogadinae is Aleiodes.
The mummy is the hardened, thickened skin of the last larval stage of the host before death. The rogadine parasitoid undergoes its pupal stage inside the mummy, using it as protective shelter.
