          Abstract

          A new species of a gregarious Meteorus wasp (Braconidae) constructs an unusual cocoon mass. Meteorus restionis sp. n. is described and distinguished from similar species. Cocoons of M. restionis are dark-brown, ovoid, and they are attached perpendicularly by their posterior end along a long, suspended cable. The cable is formed by intertwined, independent threads which are glued together at irregular intervals along its length, suggesting a certain degree of cooperation or at least tolerance among larvae during the construction of the cable. Intertwining and gluing the individual threads in a single cable presumably gives it a greater resistance against wind and other environmental stress. Prior to emergence the wasp cuts a neat, circular cap at the anterior end of its cocoon, and the cap remains attached by some threads to the rest of the cocoon.
