I'm finding nibbles on my jade plants and echeverias lately, and found the culprits: little beetles around 7 mm long. Any bug experts out there who can tell me what kind of beetles these are and how to best control them? I'm now using systemic pesticide granules but that still means the plants have to get nibbled for the pesticide to work.

So far they limit themselves to crassulas and related plants, and ignore cacti, agaves and haworthias. For now. I've been shaking them out of the plants at night when they're out feeding (easy to do because they fall off and play dead when disturbed) and stomping them, but I'm sure I'm missing a lot of them.

Thanks for any help you can give!
