Bonjour Dipterists
After observing and waiting for maturing larvae of Ceratopogonidae
I wish to determinate as deep as possible the spc
I have pictures and video regarding the three stages larva, pupa and adult, male and female

I need help to go ahead within the determination as I have no documentation to discriminate
Dasyhelea bilneata


D. flaviventris
D. littoralis
D. obscura
D. semistriata
are repertoriated in Belgium





Larva hooks
