The Early Stages of Ablabesmyia Annulata (Say) (Diptera, Chironomidae)

Abstract

The larva of Ablabesmyia annulata is remarkably similar to Malloch's Tanypus sp. A, briefly described in 1915. It differs from other American species in the following characteristics: 3 inner teeth of lingua truncate, all claws of posterior prolegs yellow, and both anterior and posterior prolegs apically and densely armed with spinules. In the pupa, the respiratory organ is smooth and ovate, lacking a terminal papilla. The respirtory opening is distinctly preapical. The species is widely distributed in Ohio.
