Oh my gosh, in my post about the Say's phoebes eating ground bugs, I said that
they were box elder bugs. That's not right! They were earwigs! I had terrible
infestations of earwigs over the last few years and they're hard for me to
manage so I was glad when they didn't seem to be a problem this year even
though I saw the big hatching.
So, do you think that if phoebes would go after the earwigs?
Thanks, Deb Carstensen, Littleton, Arapahoe county
