Silvery Checkerspots flying for about ten days by this time… concern as has been for years, the population here seems very isolated, & this species may be gone from some adjacent states, by all accounts. Tailed-Blue on a 2nd ‘summer’ brood, just starting here. Satyrium hairstreaks just getting started here, with Red-banded Hairstreaks out for some time. Hackberry Emperor seems regular, if a bit scarce - ? - here in recent years. A look in a few areas here for grass-skippers was not fruitful, will try again at some point - much of former small habitat patches for those has succumbed to rank weeds such as mugwort, bittersweet, and other pushy plants; native bunch grasses have suffered greatly. The first of Little Wood-Satyr, which here seems to have only 1 brood, in the summer season. Nectar sources still a bit minimal, other than on open & not-all-mowed fields, but some patches of dogbanes have been in bloom, and some common milkweeds just about to bloom. Weather has lately been much more conducive to emergences.
