Happy Boxing Day, everyone! Just needed something completely different from snow and old barns. Dug deep into my archives and came up with this macro of a leaf tip of a Venus Flytrap plant. A splash of colour feels good today - a sunny day, but with a temperature of -18C (-0.4°F) with a windchill of -24C (-11.2°F). This macro shot shows the trap slightly open. I'm not sure why some traps are green and others more yellow, orange or red, but I've had all these colours on one single plant. Perhaps they change colour with age? This leaf tip was somewhere around half to three-quarters of an inch long. "The Venus Flytrap, Dionaea muscipula, is a carnivorous plant that catches and digests animal prey—mostly insects and arachnids. Its trapping structure is formed by the terminal portion of each of the plant's leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike. The requirement of redundant triggering in this mechanism serves as a safeguard against a waste of energy in trapping objects with no nutritional value." en.wikipedia.org/wiki/Venus_Flytrap David Attenborough looks at how this well known carnivorous plant captures its prey.

I came across this photo last night, when I was trying to find a photo that had some bright colour in it. I cropped it, but found the darkish grey-blue background so unpleasant. Normally, I don't change backgrounds, and with the couple of photos that I have done so, I always say what I have done. Took me forever to remember how to do it, too. Anyway, this image shows two different leaf-tip colourings that were on a Venus Flytrap plant, taken on 29 July 2014. The tips were maybe half to three-quarters of an inch.

I haven't driven anywhere since before the storm, so still haven't seen "the big picture". Just on my street yesterday, city crews were out on foot, marking the trees that needed branches removed. Now the edge of the street is lined with endless piles of cut branches, waiting for the trucks and equipment to come and deal with them. And that's just a tiny section of my street - makes you realize how many thousands of trees were damaged across the whole city. Not sure what happened to the sun today, as the sky is very overcast. It's supposed to return tomorrow, though. Later: it rained this afternoon, which helped get rid of more of the snow, but I suspect that down in our parks and natural areas there will be still be snow and slush. The weekend is looking good so far : )

This is a macro shot of a leaf tip belonging to a Venus Flytrap plant. In this photo, the trap is slightly open. I'll add a previously posted photo of an open trap, and of a white flower, in a comment box below. I'm not sure why some traps are green and others more yellow, orange or red, but I've had all these colours on one single plant. Perhaps they change colour with age? This leaf tip was somewhere around half to three-quarters of an inch long. Though I tend to think of Venus Flytrap as being a tropical plant, it's not.

This is such a fascinating, carnivorous plant! Much smaller than my photo shows, of course, as this is a macro shot (taken in my kitchen, by the way!).

This leaf tip was maybe three quarter's of an inch across when open, as in my image.

"A vast treasury of wildlife images has been steadily accumulating over the past century, yet no one has known its full extent - or indeed its gaps - and no one has had a comprehensive way of gaining access to it. ARKive will put that right, and it will be an invaluable tool for all concerned with the well-being of the natural world."

Each of the Venus Flytrap leaftips seemed to be a different colour, some green with a faint touch of pink and red, and some red with stronger rainbow stripes. Hard to imagine something that can look so delicate and pretty being able to close and crush an insect for its next meal. This leaf tip was maybe three quarter's of an inch across, when open, and the same in length "The Venus Flytrap, Dionaea muscipula, is a carnivorous plant that catches and digests animal prey—mostly insects and arachnids.
