Location and Habitat
Location Accuracy (meters):
0-25
Habitat Type:
Developed - Sub/urban areas; parks/gardens
Habitat Type Notes:
Wooded residential yard. Same parcel within which larvae and pupae had been observed within the last several weeks, presumably utilizing "colony trees" (sweet gum, tulip, trunk diameter> 12", south -facing side only). This adult was *not* directly associated with trees described above, but was found silent and at rest on house siding in close proximity to trees (>/=8 ft).

Observation Notes:
Same parcel within which larvae and pupae of this species had been observed within the last several weeks, presumably utilizing "colony trees" (sweet gum, tulip, trunk diameter> 12", south -facing side only).
This adult was not directly associated with trees described above, but rather was found silent and at rest (during daylight hours) on house siding in close proximity to such trees (>/=8 ft).
Note: I recorded flash pattern video from approx 10 hrs later. Not directly associated with this individual, but much activity consistent with Pb. (Delicate, quick, and regular amber flashes *very* high up amidst the nearly bare branches of the same mature hardwoods (~50 ft+ ?) described above.)
