Description of adults: Description from Kozlov, 1989: "Mouth apparatus with well-developed mandibles. Maxillary palps long, geniculate. Pronotum relatively large, its length equal to maximum diameter of eye. Forewings with a CuP stalk and two anal veins; CuP and A1 connected by crossvein near base of wing, crossvein between A1 and A2 located somewhat more distally; A2 extending into A1 forming an anal loop."

Distribution:

The genus is known from the late Jurassic in Kazakstan and from the Glushkovskaya series from Transbaykal at the Jurassic-Cretaceous boundary.

Biology:

Nothing is know about the biology of Daiopterix-species.

Stages in development:

The early stages are unknown.

genitalia. In Daiopterix olgae Kozlov, 1989, the tips of the anterior apophyses reach at least the distal margin of segment VII, whereas the posterior reach abdominal segment III (Kozlov 1989).

Species of Daiopterix differ from Eolepidopterix Rasnitsyn, 1983 in Sc2 of the forewing reaching the costal margin proximally of the branching of the radial stalk. In Palaeolepidopterix Kozlov, 1989, Sc and R1 reach the costal margin distinctly more proximad. Furthermore, Palaeolepidopterix has a well-developed jugum, bearing a cluster of hairs.

Phylogeny: The enlarged pronotum and the long apophyses posteriores has lead to an assignment of Daiopterix to the Eolepidopterigidae. Whether one of the two features can really be regarded as an apomorphy of that family, remains unknown.

Worth knowing:

The age of the two known fossil species of Daiopterix is estimated to be about 155 - 112 Ma.
