(Citheronia regalis overall spotty distribution

Tue Nov 2 06:45:09 EDT 2010

I have looked at a lot of butterfly range maps on BAMONA, but the Citheronia regalis distribution map seems unusually spotty.  Is it just that the moth disappeared from intermediate sites before it was recorded.  

http://www.butterfliesandmoths.org/species?l=3334   [I can't seem to copy this map, so check the site]

It's not as host specific as I had thought (see below). And I wonder what its various State conservation ranks are.

ADDITIONAL INFORMATION FROM BAMONA WEB SITE
Caterpillar hosts: Hickories (Carya), pecan (C. illinoensis), butternut (Juglans cinerea), black walnut (J. nigra), sweet gum (Liquidambar styraciflua), persimmon (Diospyros virginiana), sumacs (Rhus), cultivated cotton (Gossypium), and others. 

Adult food: Adults do not feed. 

Habitat: Deciduous woods. 

Range: New York west through southern Michigan and Illinois to eastern Kansas; south to central Florida, the Gulf states, and east Texas. 

Conservation: Not usually required. 

NatureServe Global Status <http://www.butterfliesandmoths.org/glossary/term/12?Array> : G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery

Hugh,

Roughly 15 years ago I was walking a path alongside an apple orchard and encountered a fifth instar C. regalis larva on a Black Walnut tree in Hannibal, NY (Oswego County). In all my time of running lights in the same area, however, I've never encountered an adult. Although it was probably a fluke, perhaps the result of a storm-blown female, it is nice to think that they may occur naturally up here.

Hugh,

The last place that Eacles imperialis is holding on in Massachusetts is on Martha's Vineyard-where thousands are in residence-an island.   Jeff Boettner at UMass is looking at Compsilura as a potential explanation.  He has some preliminary data I believe, based on sentinel larvae.

I recently had Eacles imperialis in the Clintonville pine barrens in upstate New York.  The moth occurs over a broadly elliptical area from Clintonville to Hero, Vermont (on Lake Champlain).  

Cheers

I know Leps-list is supposed to mimic the wild west, but can we stop this non-productive commentary about Monarch Watch and get back to the biology of Leps? Here are some threads I'd personally love to see discussed:

1. Anybody have some really exciting finds this past season?
2. Anybody noting any range expansions?
3. Anybody find any new exotic species this season?
4. Any undescribed species uncovered in your neck of the woods? 

I'll start:

In July I found Eacles imperialis at Montauk Long Island (NY) for only the second time ever away from Shelter Island, where the species still thrives. A little later in the month I also found 3 Citheronia regalis at Montauk, the first time I have ever had multiple individuals on Long Island. This species also only occurs on Shelter Island and at Montauk. For both of these species, I believe that these populations are the only ones that remain in the state, although Eacles may hang on in the Adirondacks.

Here's my question. Shelter Island is an island and Montauk is island-like being separated from the rest of Long Island by the open and scrubby Napeague isthmus. All of the other Saturniidae are more abundant in these two places than on the rest of LI. This has caused me to speculate that perhaps Saturniids persist here because of freedom from parasitoids, particularly from Compsilura. So my question is this: are there other islands on which Saturniids show increased abundance? And, is there any data about islands (or specific habitats) that offer relief from parasitoid loads in Saturniids?

I don't know if Monarch Watch is an up and up conservation/environmental organization or not but it is true that many so-called environmental organizations are basically just liberal democratic party lobbying groups with a top concern of providing good jobs for their staff. That becomes pretty obvious when you look at the refusal of "environmental" groups such as the Sierra Club, The Wilderness Society, the National Wildlife Federation, and the League of Conservation Voters to advocate the control of human population growth in the United States. Liberal Democratic Elites, their patrons, would not like then doing that.
