Hedgehog Galls, Ladybug
According to my own personal memory device, this is the third year I’ve noted these hedgehog galls on this White Oak (Quercus alba) in Green-Wood. This year there is a bumper crop of them.A Multicolored Asian Ladybug (Harmonia axyridis) on the galls.

Diggers
Digger wasps (Scolia dubia) hide their lights under their dark blue-black wings. “Blue-winged Wasp” is another common name for them.A bunch of these were looping over a strip of dirt on the edge of First Avenue at 41st, rather industrial ground for natural history, except for the feral cats and Paulownia and Ailanthus trees.

Once upon a time, nearly a century ago, this species was presumed extirpated from NYC, but it has clearly returned. Katydid-katydidnt & etc. The Horticulturist remembers childhood visits…

Larva
Spotted on the t-shirt of one of Brooklyn Bridge Park’s gardeners. Clearly, a bug who knows its friends. Speaking of friends, I will be doing a Bugs and Blooms tour tonight at 6:30 at Pier 1 BBP.
