Abstract
The scant information available on the mating behavior of eucoiline parasitoids stems from studies on Leptopilina heterotoma (Thomson) (=Pseudeucoila bochei Weld) (van den Assem, 1969), Eucoila trichopsila Hartig (Sychevskaya, 1974), Aganaspis daci (Weld) (=Trybliographa daci Weld) (Nunez-Bueno, 1982), and Rhoptromeris strobigena Nordlander & Grijma (Nordlander and Grijma, 1991). These authors report that males, once able to position themselves on the thorax of a female, display rotating antennal movements with simultaneous wing vibration. Such behavior was described as “vibrating and paddling” by van den Assem (1969). Wing vibration and antennal movement bouts followed by very short copulas have been also reported for the eucoilines Kleidotoma japonica Huzimatu (Huzimatu, 1940), Hexacola sp. (Simonds, 1952), Hexacola hexatoma (Hartig) and Rhoptromeris heptoma (Hartig) (Bhattacharya, 1957), and Trybliographa rapae (Westw.) (Whishart and Monteith, 1954). Aganaspis pelleranoi (Brethes) is a Neotropical larval–pupal parasitoid distributed from Mexico to Argentina that attacks a wide variety of tephritid
