Sulphur (Pieridae) Migration in Memphis, Tennessee?

[David Kesler]

My Animal Behavior class is collecting data on Sulphur Butterfly migration 
across our campus in Memphis, Tennessee.  They are collecting data on heading,
and rate of movement.  We will post these data once they are reduced.

Are there recent studies, published or in progress, with which these students 
can compare their data?  

Thank you in advance for your time.
