Amiota
Amiota is a genus of small flies in the family Drosophilidae, established by Loew in 1862. The genus contains over 100 described species with a cosmopolitan distribution, though it exhibits particularly high diversity in East Asia. Southwestern China has been hypothesized as a possible center of origin and diversification. Some species serve as intermediate hosts and vectors for parasites, including Amiota okadai which transmits the zoonotic nematode Thelazia callipaeda.
Dermacentor occidentalis
Pacific Coast tick
Dermacentor occidentalis, commonly known as the Pacific Coast tick, is a hard tick in the family Ixodidae native to western North America. Unfed adults measure approximately 4.5 mm in length with a distinctive silvery-gray exoskeleton. This species is a known vector of several human pathogens including Rocky Mountain spotted fever, Pacific Coast tick fever, and tularemia, though it does not transmit Lyme disease. The tick exhibits a three-host life cycle, feeding on a wide range of mammalian, avian, and reptilian hosts throughout its development.
Phortica variegata
variegated fruit fly
Phortica variegata is a small vinegar fly in the family Drosophilidae, distinguished by its unusual zoophilic behavior. Unlike most drosophilids, adult males feed on the lacrimal secretions (tears) of mammals, including humans, dogs, foxes, and other carnivores. This lachryphagous behavior makes it the primary European vector of Thelazia callipaeda, a zoonotic eyeworm that causes ocular infections in mammals. The species is native to Europe and has been introduced to the United States, where it has demonstrated vector competence for the parasite. Climate change is projected to alter its distribution significantly, with suitable habitats shifting toward Mediterranean coastal regions while declining in central-southern-eastern European transitional areas.
Triatoma lecticularia
kissing bug
Triatoma lecticularia is a kissing bug in the subfamily Triatominae, a group of blood-feeding assassin bugs. It is a known vector of Trypanosoma cruzi, the parasite that causes Chagas disease. The species has been documented in North America and Mexico, with records extending to northwestern Mexico where it has been introduced. Like other triatomines, it is an obligate hematophagous insect requiring blood meals for development and reproduction. It has been found in dog kennels in Texas, where it poses transmission risks to canines.
