Depending on how you count, one or the other of the species above was our 45th for the month of April (and our 46th for the year).

Will Kerling found the fritillary on the afternoon of the last day of the month, so chronologically that was the last species of the month. But soon afterwards, Jean Gutsmuth passed along a report and photos from Ro Wilson’s garden in Medford Leas where Ro had a pipevine swallowtail emerge from a chrsyalis on 4-17-12. So, that is the most recent species officially added to our log.

Both are apparently record early dates for us (joining the many earliest-ever dates we have recorded so far in this extraordinary year).

And the hot pace we have had all year continues on all fronts: more diversity, more reports, and more observers. Our total of 45 species is about half a dozen ahead of our usual total at this point (38 species in April, 2010; 39 in April 2011) and we also compiled many more observations this April than in previous years: 870 in 2010, 983 in 2011, and 1357 reports in April, 2012. (The list of contributors for April appears at the end of this report.)

Can we have still more drama in May? Well, we have:

–> a red admiral irruption in-progress;

–> more than a dozen late spring/early summer species we should probably expect very shortly, given the accelerated pace of the year;

–> four species (as Will K has noted) that we have recorded in every month so far — orange sulphur, common buckeye, mourning cloak and red admiral; can any one of them hang in there to become our first-ever all-12-months-of-the-year species?;

–> an ecological/behavioral puzzle to investigate: will the many single-brooded species that emerged earlier than usual (blueberry azure, pine elfin, hoary elfin, cobweb skipper, et al) shift their flight season or stretch it? Will we see the last of them earlier than usual, or will some individuals continue to emerge and fly to their usual late dates?

–> and last, let’s not forget that we have a number of second broods due to emerge as caterpillars in May:
