摘要
Information is presented on the distribution, life histories, and larval feeding habits of three species of Tetanocera Dumeril (T. bergi Steyskal, T plumosa Loew, T stricklandi Steyskal) that prey as larvae on pulmonate aquatic snails. Tetanocera bergi is widely distributed in the western United States and Canadian provinces, T stricklandi is known only from Alberta, and T. plumosa has a transcontinental distribution. Larvae of all three species are general feeders and consume several taxa of aquatic snails.
