[Quetzal]

I also spent some time squishing the beetles and larvae this year and discovered the reason I never noticed larvae before is because they hide!  Without my reading glasses I can't see very well but from a distance could see some dark shadows ... when I approached squinting at the smudge, it was gone so I peeked behind the stem and saw the larvae actually move away    This year I also grew pot marigold in the bed - maybe it was a combination of both hunting the beetle and the pot marigold, but there was definitely significantly less damage than in previous years 

I've noticed them hiding too, the blighters. We've got them pretty bad, although it didn't stop the asparagus from getting over head height this year (2nd year in the ground, so no picking). I might have to look into some marigolds, since my squishing fingers get tired out.
