Chaoborus astictopus, the Clear Lake gnat, is a species of phantom midges in the family Chaoboridae.^[1]^[2]^[3]^[4] The older larvae are commonly found in the profundal zone of lakes during the day and in the open waters at night, suggesting that they are negatively phototactic.^[5]

The larvae can be vulnerable to the pathogen Thelohania corethrae during the winter season.^[6] They are also susceptible to the fungal pathogen Tolypocladium cylindrosporum.^[7]
