Since 2002, the laboratory of Steven M. Reppert has used anatomical, cellular, molecular, electrophysiological, genetic and behavioral approaches to more fully understand the biological basis of monarch butterfly (Danaus plexippusmigration, with a focus on the butterfly's navigational abilities and its distinctive circadian clock.

 

Since 2015, the Reppert Lab has refocused its research efforts to include the neurogenetic basis of cocoon spinning behavior by the larva of the cecropia silkmoth (Hyalophora cecropia).

 

Take a look around to learn about monarch and silkmoth biology and to discover the many open questions our lab continues to explore.
