By the way, Paul K wrote : "French Guiana was indeed a paradise for collectors and researches until July 2019 when French government introduced new law which restricts collecting to 100 specimens per year per person."
There is currently a great mobilization of French entomologists and their associations, both in Guyane (SEAG) and metropolis (SEF, ACOREP, ALF and so on). Negotiations are in progress with the local authorities (prefecture). It is very likely that the statutory texts will be changed in the right direction. The task of the authorities concerns especially the massive outflows of the territory of Guyane large arthropods like Theraphosa blondi and Titanus giganteus effected by collectors from the countries of Eastern Europe for commercial purposes. It is obvious that there are no common measures between 100 Titanus giganteus and 100 micro-Lepidoptera or 100 Rhopalocera. Quotas will certainly be modified in a good way.
Anyway, at the airport in Cayenne, customs officers have so much to do with "mules" (those who swallow drug sausages) that they have little leisure to deal with insects.
SEAG = Société d'entomologie Antilles-Guyane SEF = Société entomologique de France ACOREP = Association des Coléoptéristes de France ALF = Association des Lépidoptéristes de France
All these associations are linked with the National Museum of Natural History.
