Insect Migration

Most people think of Monarchs when asked about insect migration.  But we are learning that other insects migrate, and this year the Xerces Socisty is starting a citizens' survey on the black saddlebags
dragonfly migration.  This black saddlebags was photographed on Sep. 12th, and appears to be an immature (more yellow bands). 

Another was photographed on Sep. 23rd, and also seen swarming with it were common green darners.  The young black saddlebags are apparently migrating south, but more needs to be known about this insect migration.
