To go collecting in French Guyana, the period must be chosen according to what you want to collect, because we don't find everything anytime :

  • Best mothing are in January-February (and you could collect Titanus giganteus if you are lucky…),
  • Best butterfly collecting are during the dry season, in October-November,
  • To collect Morphos, best period is May
  • Best period for Nymphalidae trapping (Prepona, Agrias) is July-August
  • To collect Cerambycidae, August-September seams to be the best period
  • Megasoma acteon can be collected in June (I collected myself a female in July)

Anyway, there is no local abundance of a particular insect specie in French Guyana, due to the large diversification of tree species.
