Your letter to the bugman:  Our artichoke plants are infested with these strange looking bugs. They are on artichoke plants quite far apart, but no other plants. Looks like some sort of lice (?) with a very strange tail which they use to cover/camouflage their bodies with. They are eating the plants fast and causing quite a lot of damage. Approx 5mm in size.

Thistle Tortoise Beetle Larva

Dear Matilde,
These look unmistakably like Tortoise Beetle Larvae that carry fecal matter on their back for camouflage.  We did some research and found several French language sites, including Natura Mediterraneo and Agraria that identify these as the larvae of the Tortoise Beetle
Cassida deflorata.

Thank you so much, that makes perfect sense, when we first saw them we thought they were droppings. Upon further research it appears they are
Thistle Tortoise Beetle Larvae  which makes sense given that they were on the artichokes only.
Thanks again
