Abstract
Abstract. Daily abundance at the breeding site and reproductive behavior of Polythore gigantea
(Selys, 1853) are described in different localities of Antioquia, Colombia. Observations were
done between March and June 2009 from 08:00 to 16:00 h. The highest reproductive activity (i.e. maximal abundance of individuals at the breeding site) was observed between 11:06
and 12:12 h. Oviposition lasted 10 min on average. During courtship, the male exhibited
rhythmical movements by opening and closing the wings rapidly, getting closer to the female
and holding her in tandem. During oviposition, the female inserts the eggs inside wet trunks
and little twigs in the surrounding vegetation under the close surveillance of the male. Males
exhibit territorial behavior and conspecific aggression to defend the territory. Factors such as
vegetation cover, might influence the time of the day in which oviposition occurs. This study
provides, for the first time, information on the reproductive behavior of P. gigantea.
