What are these insects on these french spoons and forks?

[cfauvel]

so on the forks and spoons, of which I'm trying to find the silversmith, on the topside are marks that appear to be insects.
I did not find anything remotely similar in my research.
They all seem slightly different and they are not bound in a cartouche or diamond.

They all have the Minerva stamp and I think they are from the late 1800s

Thoughts?

Ok one more question on this subject.

HOW DID ONE CARVE OUT SUCH INTRICACIES IN SUCH A SMALL SCALE?!?!

Seriously baffled by that ...you can see the leg thorns and abdomen segmentation.
