I’ve been raising some silkworms from Cambodia. They’re Bombyx mori, same as all the other domesticated silkworms – but they’ve been bred for centuries to withstand the particular stresses and hardships of Cambodia’s hot, humid climate. They are MUCH smaller than most of the regular strains, and they make a brilliant yellow cocoon.
