Abstract

Flight of the range caterpillar occurred predominantly at dusk in the grasslands of eastern New Mexico in 1979 and 1980. The restricted period of flight in the evening corresponded to cool temperatures which probably favored mating success. Changes in atmospheric temperature and pressure had little effect on the number of moths flying from day to day. Most females oviposited within 10 m of the site of pupal eclosion.

Résumé

Le vol du saturniide Hemileuca oliviae Cockerell a surtout été observé au crépuscule dans les prairies du Nouveau Mexique en 1979 et 1980. La période restreinte de vol au cours de la soirée était corrélée aux basses températures qui favorisent sans doute le succès de l'accouplement. Les changements de température et de pression d'un jour à l'autre ont peu affecté le nombre de papillons volant. La plupart des femelles ont pondu dans un rayon de 10 m autour du site de leur émergence.
