Larva: A Mansonia titillans larva is medium-sized. Head capsule width ranges (mm) of 0.30-0.35, 0.47-0.58, 0.79-1.06, and 1.25-1.49 have been documented in field-collected first, second, third and fourth instar larvae (Nemjo and Slaff 1984).
Aug 19, 2021 · Larva. A Mansonia titillans larva is medium-sized. Head capsule width ranges (mm) of 0.30–0.35, 0.47–0.58, 0.79–1.06, and 1.25–1.49 have been documented in field-collected first, second, third and fourth instar larvae (Nemjo and Slaff 1984).
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. Adults
LARVA (not illustrated): Head: Antenna length about equal to head width; head with a prominent pointed projection under base of antenna. Terminal segments: Spiracular apparatus modified for piercing plant tissues; segment X with multiple sharply-pointed, stout precratal setae.
Jan 1, 2010 · An exception, as with the siphon of the larvae, can be found in the genera Coquillettidia and Mansonia. In this case, the trumpets taper apically and have a strong sclerotized hook, adapted for piercing submerged parts of aquatic plants.
The larvae of Mansonia resemble those of Coquillettidia in having a sclerotized saw-toothed process at the tip of the siphon, which is modified for piercing submerged parts of aquatic plants to obtain oxygen from the aerenchyma.
