I accessed the Robert J Iveson collection at SUNY Brockport and photographed the "Eastern Tiger Swallowtail" specimens. My apologies for the dark images; I can lighten them but thought it better to leave as-is.
Notably, Bob lives in Brockport, which along with nearby Holley and Bergen are in the northwestern corner of the Finger Lakes region, in other words not far from Lake Ontario. However, there are specimens from Adirondacks, Catskills, and PA- apparently corresponding to family trips.

Below is a summary, sorted by location then date:
For a geographic understanding of Bob's Finger Lakes records, the map is updated to show Brockport, Holley, and Bergen. I've also added Webster and Victor for future discussions.
The following sorted by location, Finger Lakes region first. Note from the map that Brockport and Holley are adjacent towns; Bergen isn't far.

In examining the Finger Lakes specimens (line items 2 through 10) Bob had only nine specimens, so not a great survey size. Note though that he had only ONE specimen later than mid-July (12 August) which is dated 2001. This is perhaps indicative of something (and certainly reflecting my own records)such as a univoltine flight ending by early July- until about 15 (maybe 20 now?) years ago. Or it could be just the sample size.
