Hi, this one was quite big, some 18 mms, between fallen leaves. What could it be?

I think Anisopodidae, for the abdominal segments are subdivided into (I think) 2 segments, leaving a false impression that the abdomen has 16 segments instead of the normal 8. |

That is interesting  Do You think they will pupate soon? Or maybe only in Autumn?Regards, Walter Walter Pfliegler - Amateur Nature Photographer from Hungary (and molecular biologist) |

Sorry, No idea when they will pupute, but it looks to me as if it's a third stage larva. |

No - this is clearly a therevid - the metacephalic rod is spatulate, and this is clear in the photo. And it has the right secondary segmentation. Nice! |

Thanks. I have two specimens. What do they eat?

This may be Therevidae. Body segments subdivided but its subsegments approximately equal to each other (not narrow ring and wider second part). Head is sclerotised dorsally only. Besides you can see dark metacephal rod (character typical for Orthorrhaphous larva) posteriorly from head capsule which is broaded (character typical for Therevidae). To make sure finally please look if it has 2 papillae posteriorly (Anisopodidae have 5-lobed posterior end with posterior spiracles like Limoniidae) and Therevidae have popsterior pair of spiracles on lateral sides of segment. If it is Therevidae then it is predator. It needs some damaged a little fresh larva to eat before pupation (or ant eggs or something like this).

P.S. Put them in separate tubes. they may eat each other. |

Hi, meanwhile one of the larvae produced black spots on thorax:

And, finally, the other larva is already a ~7 mm long pupa!
