A form of the disease, termed "jungle yellow fever", was shown to be carried by Red Howler monkeys (Alouatta seniculus insulanus Elliot) that provided a continuous reservoir for the disease, which was then spread by the Haemagogus s. spegazzini mosquito which normally inhabits rainforest regions, both at ground level and in the treetops.
Adult females have been recorded biting humans during daylight hours, [1] usually attacking the lower body.
