Re: Canada to US?

Papilio ponceana is the new name. Also, is P. indra kaibabensis protected?

Re: Western Tiger Swallowtail (Papilio rutulus)

Also worth mentioning is that the larvae of pilumnus, troilus, and palamedes are similar. They also all primarily feed on Lauraceae as caterpillars. Papilio pilumnus uses Litsea.

Re: Distance caterpillars travel to pupate?

Yes I agree, different species have different tendencies to travel. Like mentioned earlier, some species crawl off the host plant but others pupate or spin cocoons on the host and hardly move.

Re: Distance caterpillars travel to pupate?

But it still travels some more, so there is no set distance. If you took 10 caterpillars and they were clones, there is no way they would all travel exactly the same distance. Mayne one travel during a hot day and another during a rainy cool day. There are many factors. The distance is not going to ...

Re: Distance caterpillars travel to pupate?

I don’t think the distance is set. If a larva is making a cocoon, and you take it and move it somewhere, it doesn’t crawl that same distance all over all. If crawls a much shorter distance and makes a second cocoon much sooner because it’s running out of time.

Re: Distance caterpillars travel to pupate?

Yes, there are many factors, not just the ones I mentioned. Body size certainly counts. All of this is to say that distance is highly variable but some species can crawl many meters (double digits) to pupate.

Re: Distance caterpillars travel to pupate?

I have raised numerous species and how much time the larva spends wandering is species dependent. If you assume caterpillars crawl 1 cm every 3 seconds and they crawl for 6 hours, then you are looking at 72 meters. Of course, they don’t crawl in a straight line, sometimes they double back, and the c...

Re: Eurytides marcellus

You must be talking about me lol. There are also a couple of records from northern MI (probably same individual) and Point Pelee in Ontario. It’s not that it can’t survive here due to the winters, it’s mainly lack of pawpaw. Historically, marcellus was a resident breeder in Ontario before 99% of the...

Re: Paplio joanae or polyxenes?

Are we sure those are joanae in the pictures? The paper I linked above says joanae and polyxenes are indistinguishable by morphology alone. Certainly, the eyespot does not match any of the 4 type specimens.

Re: Paplio joanae or polyxenes?

Looks like polyxenes. I have seen specimens where the yellow/orange ring is thin and slightly incomplete and the pupil is relatively large. However, the pupil would still be circular. In contrast, the pupil in joanae is a bit flat and the long axis of the ellipsoid is horizontal.

Re: Tiger Swallowtails of NY: Finger Lakes, Part II

Hey Chuck, my 2 cents is to wait. Like I said before, actual reviewers will be more nitpicky than me! Many times, it’s not necessary to have something conclusive in order to publish. You can publish anything that’s new. However, your case is a bit different. It’s not that you have completed one proj...

Re: Islanded Endemics

Joanae and polyxenes are not reliably separated visually. How many of those old specimens “identified” as joanae but look like polyxenes are actually joanae?
