July 2, North Beach: Red admiral butterflies are abundant in the yard. Some species of butterfly hatch multiple broods during a season. Red admirals have two or more broods in our region. One brood must have just hatched because so many are around. They are one of the widest-spread species on the planet. There is also plenty of Calvert County’s official insect, the zebra swallowtail, flying about. The weather is surprisingly cool, a nice break from the recent heat. But it is going to get hot again.
