This study disrupts optix in Manduca sexta and finds it regulates abdominal pigmentation, replacing orange with black eumelanin, suggesting optix modulates an alternative pigment pathway.

This study examines how floral temperature and humidity in squash flowers affect pollen viability and pollinator behavior, finding that reduced humidity harms pollen and alters squash bee visitation.

This study examines osmoregulation in hawkmoths under varying humidity and nectar conditions, finding that osmolality levels and survival are significantly affected by environmental factors and feeding.
