CONT

Les principales causes de tactismes positifs (attraction) ou négatifs (répulsion) sont la lumière, la chaleur, le courant électrique, la composition chimique des eaux, les odeurs. Certains de ces agents créent un champ : un animal peut nager vers la lumière sans recevoir plus d'énergie. D'autres créent un gradient : l'odeur du papillon femelle, une phéromone qui attire les mâles, augmente la proximité.
