Island Bugs
Ah, summer, season of buzzing and flying and biting! The insects are out in force. OK, there’s really not that much biting, per se. Seen last week on Nantucket: One of the green metallic bees, genus Agapostemon, also known as sweat bees, on chicory flower. Note the big bundles of pollen around the legs. A…

City Habitat
Now that the dog-day cicadas have started to emerge from their years underground, their enemy, the cicada wasps, emerge as well. And since our street trees have roots, which is what the cicadas live on while during their nymph stage, so too do our streets have these wasps.Yesterday, walking in Brooklyn Heights, I found a…

Furman St. Cattails in Summer
Back in March I noticed some improbable cattails growing from the roof of an old garage on Furman Street, underneath the Brooklyn Heights Promenade. I recently walked by again, both underneath and above.I think there might be some pragmites up there as well.

Ladybugs
NSFW? Variegated ladybugs, Hippodamia variegata, making more beetles. Photo taken on Bond Street by the Gowanus Canal. Quite a bit of action, so to speak, on these leaves. Note the eggs below, the aphid (?) on the left, and the remains of something by the female beetle’s front right.
