Hi Derek,
Not trying to pry any state secrets out of you, but it would be interesting to know generally how you sample these after-dark critters in out-of-town areas like Mt Uniacke -- do you run a mercury vapour light trap off a portable generator, or do you use one of the less powerful 'black light' (UV fluorescent) tubes that can be run off batteries? If so in the case of the former, do you worry about UV exposure (eyes, not skin)?
When I was a kid (in UK) we also used to use 'sugaring', painting strips on trees at night along a pathway in a wood with a concoction of molasses, beer or other alcoholic beverage, while just before use adding a few drops of 'essence of pear' as I recall (maybe amyl acetate?). We'd do the rounds several times over a couple of hours, usually finding a few drunk noctuids at some stations, but it was never as productive as light trapping. Does anyone still use sugaring?
Might be interesting for folks on this list to know generally what techniques work best for moths or other insects, away from the home's or camp's porch light, and also how you avoid being accused of deer jacking if using a powerful light trap at night in the countryside (seldom a problem back then, in UK).

Hi Derek & All,
There are large areas of Larch in Hants Co. and I notice this is not in your distribution list. A soils map would be a good initial guide and depressional terrain of Queens soil would likely have Larch.

Hi Nancy & Jim
I have had an interest Hyalophora in NS for some time and they are more common than previously thought to be . They are known from Cumberland , Colchester, Halifax , Queens, Kings , Lunenburg , Annapolis and Victoria Counties in NS . The range of Hyalophora columbia in NS is limited by dependency on larch as Jim indicated is the larval food plant and predominates in low lying boggy areas. Although many counties have larch present from which columbia has not been reported over the years – I believe this is likely a sampling artifact.
Like all Hyalophora species, columbia is univoltine and usually flies from May to early June depending on spring time warmth.
I have seen female moths as late as mid July in some years.
Female columbia can usually be seen at lights after 10:30 pm, but males, which also come in to lights, are rarely seen because they usually don't fly until just before dawn and will fly away or be eaten by birds as the sun rises.
Male columbia are seldom seen because they are seldom seen at lights. The calling time of the females is at dawn. Females do come to lights, but not as frequently as females of some other Saturniidae species.
A couple of questions Nancy just out of curiosity – what were the sex of your two columbia and what type of habitat is your camp at East Dalhousie around ie larch ? ?
Thanx for the update. Also any cecropia flying at your camp yet ?
Look fwd to your moth updates as they happen and hope you find this info helpful
Cheers – DB

Two Columbia on the veranda post this morning. The Peterson's Guide calls them uncommon but perhaps they are not in our area.
Nice to view all these large moths lately. A tattered Luna was also on the side of the camp at ground level this morning.
