We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30, with coffee and refreshments. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club acitivities, club business, social time, nature sightings and reports.

The club also offers a full schedule of outdoor activities during the year. Through these outings, members learn more about the birds, plants, mammals and geology of this part of Ontario. We also keep a protective eye on our precious natural areas.

Introduction to How to Attract and Identify Moths.

August 4, 2021 @ 9:00 pm 11:00 pm

A Moth Night – An Introduction to How to Attract and Identify Moths
When: Wednesday August 4, 2021
Time: 9 pm – 11:15 pm (Aug 5 – Rain Date) plus Thursday August 5 at 7 am to open Moth traps for ID, Photos and Release
Where: Grey Sauble Conservation Administration Centre and Arboretum, 237897 Inglis Falls Road, RR 4, Owen Sound, Ontario N4K 5N6

Alan Macnaughton has good equipment and techniques for attracting moths, and he can show other people how to do it. He will set up several stations and use several lights (black light) and bait (rotting bananas). It will be an excellent opportunity to learn various methods of attracting moths. 

To register – please contact: jwdickso@gmail.com  Priority will be given to OSFN members, but please register early to avoid disappointment. 

Due to COVID-19, Public Health Guidelines will be observed, including masks and social distancing.

Extra information – Guests of OSFN – Area members of the Toronto Entomologists’ Association may be joining us.

Equipment –
Bring cameras or phones for taking pictures and perhaps some transparent pill bottles to temporarily capture the moths for handing around to others before they are released. Phones are often best because they may have an internet connection (is this possible in the park?) to allow uploading observations to the www.iNaturalist.ca website for automated (image recognition software) species identification. Also, if they happen to have it, bring the Leckie and Beadle book, Peterson Field Guide to the Moths of Northeastern North America. One of the lights is bright and some people might want sunglasses when they get near it.

Binoculars are not needed. You will be able to touch the bugs.
