NEARCTIC & NEOTROPICAL REGIONS
Etymology: not stated [tipulid-like; “Several species of tipulidae (sic) closely resemble it on the wing”]
Mansonia titillans, the type species of the genus Mansonia, can be a severe biting nuisance in parts of its range. Dense populations flourish in Florida, where populations peak in late fall. In the United States, the species geographically overlaps with and is often confused with the morphologically and biologically similar species, Ma. indubitans Dyar & Shannon and Ma. dyari Belkin, Heinemann & Page.
Type locality: Belém, Para, Brazil
Type depository: Natural History Museum, London, England, United Kingdom (NHMUK)
DIAGNOSTIC CHARACTERS (Click photos to view; mouse over and click large photo to zoom in.)
ADULT (illustrated): Head: Proboscis with a distinct postmedian white band; Flm1 with patch of broad dark scales medially. Thorax: Postspiracular setae (PS) present; supraalar area (SaA) with elongate scales with simple apices. Wing: With distinct white speckling, scales broad and asymetrical. Legs: Ta-III1 without a median pale ring. Fe-I–III speckled, without distinct preapical white band anteriorly. Abdomen (♀): VII-Te with row of short spiniform setae; VIII-Te with group of robust spines posteriorly.

Terminal segments: Comb scales with a strong primary spine and a few small spinules; seta 1-VIII short and multi-branched; modified spiracular apparatus for piercing plants; seta 1-X short, multi-branched; seta 4-X with 4 precratal tufts.

Ma. titillans COI: KT766518–37, KY859898–902
Typical immature habitats of Ma. titillans are marshes, lakes or large freshwater ponds that support high densities of aquatic vegetation. Mansonia larvae and pupae attach to the stems and roots of aquatic plants—especially Pistia sp. (water lettuce) and occasionally Eichornia crassipes (water hyacinth) to facilitate respiration.
Both male and female Ma. titillans are often captured in CDC light traps. Although female prefer mammals (including humans), it also attacks birds and alligators in Florida. In Guatemala, 90% of all bloodmeals were from equines and cattle. Female Ma. titillans oviposit underwater, using the spines on the VIII-Te to rasp the underside of the submerged/floating leaves for egg adhesion. The rosette-like egg masses are then enveloped in an air bubble and transported under the leaves using special adaptations on the female abdomen.
