Mariana is first author on a collaborative paper presenting the results of our first season of rearing of silver-spotted skippers where we used the data to develop a predictive model of phenology. In a collaboration with Martha Weiss and John Lill, we tested those predictions in caterpillars developing outside as part of a field experiment. Predictions worked best when we took food quality into account, but only during the summer when day length was relatively constant. Things got interesting as summer turned to fall and day length was becoming shorter. The paper is being published in the entomological journal Entomologia Experimentalis et Applicata
