nice fotos ! But my question goes towards the size of the little monsters. 0,3 to 0,5 mm stays verry well for larva of mites. These than could be 6 leged spider like animals suposed to have 8 legs.
So it is a speciality among acari larvas having 6 legs at the beginning. Also the habitus of the kritters speak for mites.
no problem at all. This are mites in my opinion and they are no insects. What i wrote as spider like animals means arachnids or archnoids and they are among ticks, scorpions and spiders 8 leged arthropods, while the 6 leged ones are insects. The exeption that larvas of mites are 6 leged makes it not easyer, grin.
For you and us it is more important you make nice fotos. OK ?
