Size
Medium-sized mosquito.
Identification
large dark mosquito - FMEL
- banded abdomen and legs - FMEL
- base of proboscis has wide pale band - FMEL
Adult: Medium-sized, dark brown or dull black in color. Proboscis dark on apical quarter, remainder yellowish, although dark scales present at base. Femora with narrow subapical pale ring, tibiae liberally sprinkled with white scales, 1st tarsomere with median stripe, and all tarsomeres with basal white stripes. Wing veins with dark and pale scales intermixed.
Larva: Antenna much shorter than head, Setae 5-C and 6-C with four or more branches, base in a straight line to 7-C, siphon moderately inflated (bulbous) medially, 3-6 widely spaced pecten teeth, Seta 1-S as long as apical width of siphon.
Range
e. US to so. CA (1) / W. Indies / Mex. to S. Amer. (Meisch 1994)
reaches its greatest abundance in the rice growing areas of the southwestern U.S. where astronomical numbers, similar in magnitude to the production of saltmarsh mosquitoes, may occur. (Meisch 1994)
Habitat
Larvae in temporary and permanent pools, with grassy or wooded margins, often abundant in rice fields.
Differing accounts say that oviposition occurs on rank vegetation surrounding pools, or on bare mud.
Season
Multivoltine in parts of their range, depending on rainfall.
Food
Larvae: Filter feeders
Adults: Males and females feed on nectar, females said to seek bloodmeals from any warm-blooded host, especially cattle.
Life Cycle
Overwinters as diapausing egg. Eggs can withstand desiccation.
The females are furious biters in day or night. Hosts include any warm blooded animal; however bovine blood seems to be preferred. (Meisch 1994)
