Two pictures of a procession of larva.
On our French forum, we think they are Diptera and somebody mentioned this behaviour about Sciaridae.
What do you think of it?

Such phenomena is known for Sciaridae. They can form rings about 1 metre in diameter like this in Europe on litter. Dark black head and transparent body integument are additional evidence that they are to be Sciaridae.

Really interesting ! It was a species described from Poland which larvae are walking in procession Sciara militaris Nowicki, 1868 (Der Kopaliner Heerwurm und die aus ihm hervorgehende Sciara militaris n. sp. – Verh. naturforsch. Ver. Brunn. – Brunn, 6 (1867): 1-69) Wink

Hello,

Thanks for the confirmation. Note that those pictures are from Madagascar.

I don' t think S.m. lives in Madagascar, or does it?
