It is well established that flies have sleep-like state and share conserved mechanisms with mammals although it is still not clear whether flies have distinct sleep stages.  \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} flies show increased sleep that is particularly prominent in subjective daytime under continuous dark (DD) conditions (Fig. \ref{fig:3}c and d).  Increased sleep in \emph{DmCa\textsubscript{v}3\textsuperscript{Rescue}} flies, sleep,  however, is restored in \emph{DmCa\textsubscript{v}3\textsuperscript{Rescue}} flies  to a level similar to that of \emph{w\textsuperscript{1118}} control flies (Fig. \ref{fig:3}c and d). By measuring waking locomotor activity, we were able to confirm that the increased sleep of \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} flies is not an artifact of a generalized reduction in movement. In fact, \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} show slightly higher levels of waking activity than their respective controls (Fig. \ref{fig:3}e).  Fly sleep consists of a number of sleep episodes.  We examined whether increased sleep amount is due to prolonged duration or increased number of episodes.
