I went on a trip this past June in the BWCA that was terrible for mosquitoes. I've never been on any trip where they were that bad, even when I was a kid growing up in Florida. They were very thick. I didn't notice any landing and staying on the black netting of my blackbird, or on me in particular, even though I was wearing jet black long underwear some of the time. What they did do in droves was perch on the underside of my tarp (which is light gray). One night I laid there with my head lamp and counted, not even kidding, 150 on one side before I gave up in disgust.
When I tented, I noticed the opposite phenomenon. They were attracted to the netting and stayed there. I suspect what they were really attracted to was the warmth and wind break.
