Subject: Re: Nature Miramichi – Hybrid Cecropia X Columbia

As a rule different species of moths do not hybridize, as the chemical composition of the pheromones produced by the female to attract a male for mating usually only attract a male of the same species. So hybrids are not a common occurrence naturally.

However, a few studies using reared specimens of Hyalophora cecropia and H. columbia, the Cecropia and Columbia silk moths, have shown that male Columbia moths will mate with female Cecropia moths. I’ve also come across a few reports of natural hybridization in the state of Wisconsin, Ontario, P.E.I. and Nova Scotia, all places where the normal range of both species overlap. The Cecropia larvae are known to feed on the foliage of a wide variety of deciduous trees and shrubs, while those of Columbia larvae feed only on the needles of Tamarack or Larch (Larix laricina) (sometimes erroneously called Juniper in the Miramichi area).

In the journal, Northeastern Naturalist, Vol. 13, No. 1, 2006, there is an article entitled: A Case of Natural Hybridization Between Hyalophora cecropia and Hyalophora columbia (Lepidoptera: Saturniidae) in Nova Scotia (Bridgehouse). The following information paraphrases parts of this article:

In June, 2002, the author captured a gravid (with fertilized eggs) female Cecropia at a black (ultraviolet) light, from which he reared larvae that had some protrusions (tubercles) arising from the back of each segment that were differently coloured from the typical Cecropia larvae – the first hint that hybridization might have occurred. After pupation, twelve cocoons were kept in cold storage until May of the following year (2003) from which they were then removed to room temperature. Both male and female adult individuals emerged in June, which had the hybrid wing colouration similar to the one in Lisa’s photos. However, as it turned out, only the males of this cross were sexually viable, while the females were sterile. Judging by the wide, plumose (feathery) antennae of the individual in Lisa’s photos, it is a male, so it has the possibility of mating with a female of either species this year. I’ve never heard what the resulting generation of such a union would look like, but presumably it could be done artificially in a laboratory setting.

Another interesting fact, determined by research on the two species, is that female Cecropias “call” by emitting an airborne pheromone (which can be detected by males up to a distance of one kilometer) at or near sunset. On the other hand, female Columbias release their pheromones just once shortly before sunrise, continuing after dawn until about 6 AM. It has also been found that “virgin” female Cecropias, those who have not successfully mated at their usual time between sunset and midnight, will stop calling about midnight and resume again just before dawn when female Columbias are also calling, thus making it more likely to attract a male Columbia mate, resulting in the production of a hybrid generation.

Fascinating stuff!

Nature Miramichi – ID and information

Hi Verica,

Good photo. Such a small subject. It is in the Skipper’s often seen “jet fighter” position as if to say please take my photo! It is a Peck’s Skipper. Found across most of North America. It likes open grassy areas.

More about Skippers

Thanks for the information below.

I have also posted this on the club’s web site.

Hello Peter,

I saw a little Butterfly on my rose this afternoon. Do you know if it is the Peck’s Skipper?

Also CBC had an article that Researchers are turning to New Brunswickers for help in search for an endangered bee. The rusty-patched bumblebee the last of which was found at Pinery Provincial Park in Ontario in 2009.

They want people to photograph the bumble bees in their yard and send photos off with location information to: You don’t have to be able to identify the species yourself. The researchers will do that. It is really important to send any pictures you get. It tells them how much effort is being made. Send us all of your photos.

The only verified collection of the species in NB was in 1949 in the Fredericton area, and that specimen is in the collection of the NB Museum in Saint John.

Please pass on.

I appreciate your help with the ID.

Hi Peter,

Attached is the updated Hay Island Bird Checklist now with 193 species, for posting on the club’s website to replace the one just recently sent after the Eastern Towhee (#192) was added on June 1.

Also attached is are two photos of a Mourning Warbler taken by Rosemonde Duguay at Hay Island on June 6, 2020, which was #193 for the checklist, and her Eastern Towhee photo from June 1, 2020.
