Yesterday we posted here, seeking to encourage all that though it was -4F outside our windows, hang in there folks, because February 26th is coming, and with it snow drops and multi-hued crocuses. We enjoyed a fairly strong response to that message. Tens of millions of northeastern Americans are anxious to see this super-frigid weather vamoose.
This morning, on our drive to Chatham University, the outside temperature hovered between zero F and 2F. Out we trot further evidence that our doggedness will soon pay off. March 4th is a reasonable target date for finding Mourning Cloak butterflies on trails. They are often the very first butterfly to fly each year. I haven’t, but others have seen them flying with snow still covering its territory. They are heroic fliers, because most other butterflies will not take to the air unless the thermometer registers at least 60F. Our Nymphalis antiopa here goes through a shivering-like burst of activity, and that produces the raised body temperature needed to fly.
Last September we planted 8 pussy willow bushes, to attract Mourning cloak females. Willows are their preferred host plants. Wouldn’t it be great if they laid their eggs on those 8 willows? Whether or not pussy willows will attract them will remain to be seen, but I’d enjoy that alot!
So, March 4th, 2014 is just 34 days away. What a terrific harbinger of Spring that would be. Hike along your local trail, snowy spots left here and there…and OMG! isn’t that a…Mourning cloak butterfly, resplendent in not too worn mahogany, yellows and to top it off, sky blue spots!
