Chagasi Sandfly
A small sandfly found in northern Colombia and Venezuela that is an important vector of Leishmania infantum chagasi, causing visceral leishmaniasis in the Americas. It thrives in peridomestic environments and feeds on dogs, the main reservoir host, as well as humans.

Insecticide-treated dog collars have been used to reduce visceral leishmaniasis transmission by this species by protecting the canine reservoir.
Nose Bot Fly of Horses
A dark-bodied bot fly that deposits reddish-black eggs around the lips of horses. Larvae penetrate the lip mucosa and migrate to the stomach, then before pupation they reattach to the rectal mucosa, causing irritation and inflammation. The name refers to the reddish rectal inflammation it causes.

Before pupation, larvae reattach to the horse's rectum, causing such irritation that affected horses may rub their tails raw.
