Yeah, but insects like mosquitoes "see" heat, and most light sources
emit light in the infrared band.

It seems that mosquitoes initially follow CO2-rich airflows to find food
sources, switching to warmth/moisture/odour vectors as they home in, and
finally using eyesight to find the best place for tapping into the
victim's blood supply.

Several information sources say this: none say they use long-range
optical or IR methods of finding their next meal.
