Abstract
In this work we document a case of mass swarming of the Mexican soldier beetle Chauliognathus vestitus Champion, 1914 from El Terrero locality, within the Sierra de Manantlan Biosphere Reserve, in Colima, Mexico. Two other species of soldier beetles Chauliognathus togatus Waterhouse, 1878 and Chauliognathus sp. were observed at El Terrero, coexisting with C. vestitus, but their numbers were considerably lower. An updated list of Chauliognathus species from the state of Colima is included. Our observations are the record, to our knowledge, of the second cantharid species exhibiting a mass flying behavior among more than 450 described Chauliognathus in the world, and the first record of this behavior among soldier beetles in the American continent.

We present the first record of a mass swarming behavior among members of Cantharidae in the American continent, with a list of species of Chauliognathus for the state of Colima, including the extension ranges for Chauliognathus vestitus Champion, 1914 and Chauliognathus togatus Waterhouse, 1878 species
Adult soldier beetles that exhibited the flying mass behavior at El Terrero, Colima were identified as C. vestitus
Summary
ABSTRACT In this work we document a case of mass swarming of the Mexican soldier beetle Chauliognathus vestitus Champion, 1914 from El Terrero locality, within the Sierra de Manantlan Biosphere Reserve, in Colima, Mexico. Two other species of soldier beetles — Chauliognathus togatus Waterhouse, 1878 and Chauliognathus sp.— were observed at El Terrero, coexisting with C. vestitus, but their numbers were considerably lower.
