We have a few of several different types here, but there are definitely more butterfly flowers right now than there are butterflies. I have the feeling that the widespread, extended droughts of the past few years have significantly reduced normal population numbers. Hopefully I'm wrong and they're just running a bit late.
Sphinx moth populations are normal here, native bees are thick and there are plenty of cabbage moths. I saw my first Luna Moth in years at the park a week or so ago. It seemed to be late-emerging as well. I thought I remembered seeing those in June in past years.
