Did you notice the vulnerability that outdoor gigs put you to mosquito attacks? You got your hands full and might even loose the beat.
I was playing an outdoor gig in Daytona Beach and No-See-Ums were out and vicious that night. I had plenty of bug repellant on, but one was on the back of my neck and chewing hard. There were some low-hanging lights on one side of the stage and one was missing the gel. I backed up to that light and burned the little sucker until he decided to leave.
It would appear that you are staring at the young lady's behind, likely more distracting than bugs.
Best thing to do, take a little travel-size squirt bottled filled with sugar water, spritz a bit on your band mates when they're not looking, mosquitos won't bother you again.
