For the past two years anything I've grown in one particular spot in my garden has been overwhelmed with these things. Last year it was dill, this year it is chervil. The bugs don't seem to kill the plant, but they are difficult to wash off and render it tough to use.
The are is partially sunny, gets about 6-7 hours of afternoon sun a day, and a bit more damp than the rest of the garden. Also, I'm growing dill this year in a different area and it hasn't been bothered by them.

Any idea what they are? Is there a solution (preferably organic)?
