Midge larvae require oxygen-rich environments

True

False

The larva of most species of midges have high concentrations of a red hemoglobinlike pigment in their bodies, which helps them thrive in low-oxygen conditions.

As a result, lakes with fertilizer and waste pollution may be more likely to have a high density of midges with this pigment, known colloquially as "blood worms."
