Hello
You're doing pretty well on your identification; just a little off on the dates.
The first mark - which you call an insect - appears to be a maker's mark in poor condition. I don't think you'll be able to identify the maker from this partial mark.
Next up is the crowned A with a feathered right leg - the charge mark- in use from 1783-89.
Follows the poinçon de Jurande or date letter mark of a crowned P. You might be able to make out the two numbers above the P and under the crown: 84, 85, 86, 87, 88, or 89. To me it looks like the P 87 used in 1787. See what you think.
Then there is the parrot head discharge mark, also in use from 1783-89.
Finally the small mark that looks like a vase. This might be a poinçon de reconnaissance although your photo doesn't do it justice.
As you seem to be interested in French pre-Revolutionary marks, a good source is the 20th edition of Tardy, Poinçons d'Argent.
Hope this helps a bit.
