"La larve de Tuta absoluta a un bouclierTuta absoluta larve have a dark brown to plack prothoracal shield, and Microlechia chretieni is said have a black head (I do not know that species myself). Your larva is pale all over, my guess therefore is that it is neither of the two. Somehow it looks more like a beetle larva to me, an Apteropeda or Orchestes perhaps.
Malgré ses compétences, je doute qu'il puisse dire mieux sur cette photo ici.
