A group all about the moths of New Brunswick, and also the Maritimes. The variety of these night-flying (and sometimes day-flying) creatures is astounding, so post your images here and we'll get something going.

I would like to have a good clear image of every NB Micro (live moths) + a similar clear image of its genitalia. Obviously impossible, for me, but for starters I would like to concentrate on species that are difficult to positively ID and that are variable; species in the genera Acleris and Agonopterix immediately come to mind.
There are images of micros on MPG and there are some images of genitalia; but I believe it's important to link a specific moth with its specific apparatus.
Also sadly lacking on MPG for the moth images are the actual dates and location of the specimens; some of the genitalia images have data.
For the macros, seems only worth doing for difficult groups and for rare NB species (new, or perhaps less than 6 individuals known from NB). With good images it may not be necessary to actually retain the specimen.
The ideal situation is to be seen in "The Moths of America North of Mexico" series of books (unfortunately far from complete): keys to species, descriptive text, distribution maps, coloured images of spread moths showing the whole range of variation, full data for each image; photos of male and female genitalia with full data.
My only quibble is that the genitalia images are too small, 4mm wide for the male Plusiinae.
Genitalia of a Sensitive Fern Borer would be useful as a reference; an adult in good condition is easy to ID, but a worn individual could be confused with a Bracken Borer but the genitalia should be able to separate the 2. With the Borer and the Leaftier the primary need is to be able to link the images of the genitalia with a good clear image of the live actual moths. I know I have both species (spread) and can make genitalia preps
but am not sure if I have an image of the actual live moth to link to the dissection.
When I did my biodiversity research it was necessary to ID every moth, regardless of condition. As you can image, on a good night with maybe 1,000 moths in a trap + few boisterous beetles, some of the moths looked a tad worn. Bottom line was that I had to do an awful lot of dissections to get ID's. When I retired (13 years ago) I had to leave all these thousands of dissections. Now I have to start again!
I am certain that Don would prefer for Moths to go to you and get them already pinned. The impression I got was that Museum staff would pin them.
Next query is: do they have to be rare? Your example showed the Celery Leaftier. At present I have a Sensitive Fern Borer and a Gold-striped Leaftier. Do you want either or only rare Moths?
I just looked at Tom Murray's page last night and saw the page for Moths he couldn't ID...I wondered what he did with them.
The trick for a beginner, would be knowing which ones are rare. Most of my micros I shoot on the wall or ceiling, I don't often cool them down....only if they are in a tough area. I suppose I could shoot them and then keep them cool, till I made the ID.
Tony, how do we send them? If I freeze a 'one of Moth' I can freeze in a container, put in an envelope with info.. species, where, when and who. I can transport to NB Museum in the frozen state but that wouldn't work with mailing to you... do you have a plan as to how we can get specimens to you?
I can also offer moth occurrence evidence from another direction: galls, mines, leaf ties, leaf rolls, etc., some of which are caused by moths and some of which contain live larvae. (See the Bucculatrix leaf skeletonizer images that I posted recently.) I spend most of my time looking for and photographing such occurrences, and I spent quite a bit of time over the winter submitting images to Charley Eisemann at BG for opinion (he's writing a book on leaf mines). I hardly ever photograph at night anymore.
Stuart Tingley wrote in an earlier post"It reinforces the importance of our assembling a good collection of moth images from this region. Let's just keep posting them, even when we aren't sure what they are, as some day they may be useful to somebody studying geographic variation in many of these species!"To take this one step further I propose adding genitalia preparations for the images. This will make the identifications, and the science, much more rigorous.The emphasis should be on the micros as these are so poorly known; also worth doing for our rarer, especially new to NB, macros.I am willing to do the preparations.Although I do get quite a few species it is obvious that Joanne, Nancy, and Stuart get more and different species than I get in Fredericton.Such a project does mean that after the moth is photographed it has to be collected, saved, and finally sent to me for dissection. This may be a deal breaker.Here is an example of the type of 'end product', (can be enlarged)
Thank-you for sharing the links to the two ladies, Tony. Lynn actually explains how she reached each ID and documents everything!! Nolie's photo's are unbelievable...I would say she is a professional photographer!!
1- The ladies
I know of 2 experienced ladies, both in Ontario; and 2 others in NB that are on their way:
Ontario- Lynn Scott, http://acleris.com/dls/tn-mothindex.html
Nolie Schneider, http://mothphotographersgroup.msstate.edu/NSIndex.shtml
These pages list all the moths found in the Maritimes, listed by province as documented by the Canadian national Collection (CNC) in Ottawa.
