I'm in North Carolina and usually loose the battle with SVB but I also have plenty of the more obvious squash bugs. I haven't noticed that they do much damage even when there are lots of them around. Re SVB: this year I am trying a row cover. I started with some manual pollination but right now I have been hoping the svb are not around in the middle of the day and have left the cover partly off then. We will see what happens.

Can't answer your question. But I hold a water filled cup underneath when I scrape them off or else rip off the part of the leaf the eggs are on and put it in a Ziploc bag. I dig a deep hole far from the squash and pour the water and eggs into it. I figure the nymphs have a good chance of finding their way to a leaf if they hatch on the ground and a leaf is closeby...but I really don't know.

Yeah... and these are much smaller than any squash bug eggs I've ever seen. I might never have seen them - even checking for squash bug eggs every day - but a strong wind knocked the plants over and the leaves wound up upside down. I did leave them out there. I'll check on them frequently. Hopefully they hatch during day light so I can get good pics while they're still clustered and near the eggs. Sometimes the only way to learn something new is to experience it.

That's pretty extraordinary to hear about SVBs damaging a squash fruit. Thank you, zeedman, for your observation. Also, I believe that SVBs are native to North America. Not clear that they are anywhere else. I think fruitworms are endemic in the Gulf, but they too have moth-like progenitors. FWIW, I believe that corn borer larvae have that brown tip. Also moth-like, but they are truly international. Then again, they are really just considered a grain pest.
