Coordinator notes: Correct ID...a better term to use for butterflies (and other insects) rather than patrolling in mate location behavior, in this instance is "fleek" or "fleeking".....fl=fly; eek or eekinging=seek or seeking...this species "fleeks" (males fly to seek females with which to mate). This and two other related terms are explained in James Scott's publication, "Papilio (New Series) #14" Google this title and see if it comes up. Otherwise you can go to this website: www.mountainscholar.org (if it doesn't work, try the address with just http:// in front of it. Mike
