I tried looking at a few pics last nite on the internet. Thing is there's just so, so many possiblities that could be like your eggs.
Seems that is a common look for most of the insect egg clusters. I think i may have found the one that's mine though.. it looks just like the stink bug eggs i looked at pictures of. Now normally i would say that i've never had stink bugs at all.. but yesterday while harvesting some wildflower seeds i found a stink bug. So, it just might be those. I'm not gonna leave em on the plants to find out though. Whatever eggs i find on my plants are getting destroyed.. good or bad bugs they don't belong on my leaves.
If i do come across some real possibilites for yours when i look up other info i'll be sure and let ya know.
