Fifty beetles

I collected over fifty beetles this evening (I did brave the wasps, which appear to be goners, although I didn't go close enough to really know for sure) -- included two of the spotted beetle variety. With an infestation this severe, I am now considering just taking down the fronds. It would mean that the bed probably wouldn't survive, but with this many beetles for such a little patch (seriously, it's about 3' x 2' total, it's rather small, I was only eating a handful of spears a year) I'm wondering if I'll get any asparagus next year anyway, and I'll have spent quite a lot of time policing the spot. I can always re-establish in a few years.
