What is this maggot like creature

[cyuuu]

Hi all,

I began trying out some macro photography. i took this photo of a very small cucumber spider i found on a leaf. he spider has something strange on its back, looks like a maggot or something. Wen looking through the viewfinder it was moving around a little. Does anyone know if or what kind of parasite this is? Kinda find this interesting. i attached a photo of the spider


best regards
Cyrill

Super macro, not sure what that is, it is quite a size for the spider, Diptera maggot?. Hopefully someone here will know!
