They crawl. They go for the warmest place on your body. If you sit down in the grass, that's a bonus for them because they don't have to go too far. They also like to get under waistbands and bra straps.
When I was in the army I sat in the woods all night on guard duty, and the next day I had chiggers every-stinking-where. I mean EVERYWHERE. Way more than 100 bites. I sat in a bath of bleach and water to kill the little b-stards.
But, ever since then (about 20 years ago), mosquitoes and chiggers do not seem to bother me at all.
