After two days in a water drop on a glass slide: Still alive !!!

And finally
I did find two spiracles... on the thoracic segment level

here they are





and here is a lateral view



a last view on the cephalic part and antennae



and on the ventral side... alike locomotor belts...
something like spicules or very tiny spines




I hope this will help
Merci beaucoup
