New Dragonfly & New Moth at Tillman Road

A last-minute change of plans took us back to our old stamping ground in Western New York State at the weekend, so I grabbed a couple of hours to re-visit the Tillman Road Wildlife Management Area, at Clarence.  The WMA is described by the NYS DEC as “a wet lowland with an emergent marsh, open water, grassy fields, a deciduous swamp and hardwood forest.”

Tillman’s greatest appeal to me, over the last 12-or-so years that I have been a regular visitor, is that one never knows quite what will be found on any visit and ‘drawing a blank’ is rare.

This time, I turned up two new insect species I had never before  seen or photographed:  a male Carolina Saddlebags dragonfly  (Tramea Carolina), and what – to the best of my very limited ability with moths – I believe to be a White Spring moth (Lomographa vestaliata).  The latter sat motionless on a leaf, to the extent that I wrongly presumed that it would be some sort of ‘bird dropping moth’ but the former was on high-speed patrol along the margin of a pond and settled only briefly, each time, before doing another lap of its territory.

I’ve been very careful in identifying the dragonfly because it is very similar, in both appearance and range, to the Red Saddlebags (T. onusta) but I’m fairly confident I’ve got it right… However, as is always the case on my blogs, if anyone recognizes that I’ve made a mistake please do add a    comment below to put me right, and I will correct any error.

The various species of ‘saddlebags’ dragonflies get their name from the dark patches on the inner section of their wings, and when seen – usually in silhouette – from below, this creates an outline that looks like what the name says.

Up where we were, close to Lake Ontario, the Carolina is fairly close to the northern limit of its range, which is over the border in southern Ontario province. Even in this part of New York State, it is further north than its usual breeding range.

My other insect of the day was a rather worn-looking Red Admiral butterfly (Vanessa atlanta) which – to my surprise – was laying eggs in low, rough vegetation where I could see no trace of any of the future caterpillars’ necessary food plants.  Does a first-brood adult lay eggs randomly around an area in the hope that at least some of their offspring will find suitable food after the plants all grow?  Or was this one operating by smell (chemical sensing) and by that means actually knew the right places to leave eggs?

As for the other photographs, well I’m always a sucker for violets and I’m not going to walk past a ‘posing’ Tree Swallow, either!

Britain’s Farmland Butterflies Bounce Back from Low Numbers

Farmland butterflies have flourished thanks to last year’s hot summer, the charity Butterfly Conservation says.

The annual Wider Countryside Butterfly Survey (WCBS) recorded almost double the number of insects compared with the previous year.

Long, sunny periods provided perfect breeding conditions for some of the UK’s brightest species, it suggested.

But experts warned the mild winter could reverse the insects’ fortunes if they emerged too early for spring.

The survey has been run by Butterfly Conservation, the British Trust for Ornithology [BTO] and The Centre for Ecology and Hydrology since 2009….

Eddie’s comment:  This is excellent news!  For the past few years, there has been a dismaying scenario of butterfly numbers falling, throughout Britain.  This has largely been attributed to inappropriately long periods of cold and/or wet weather, so it is nice to see that a warmer, drier summer brought numbers back up, perhaps to a larger extent than one might have dared hope.

As for the excellent photograph by Tim Melling, some experts say that the European Small Tortoiseshell (Aglais urticae) is actually the same species as North America’s “Milbert’s Tortoiseshell” (Aglais milberti).*

The other two North American tortoiseshells (‘California’ and ‘Compton’) are in a different genus — Nymphalis — the same as the Mourning Cloak.
