Long-legged beauty

Well at least I think so!

Eyes on you

Eyes on you

During the past couple of summers here in Wisconsin I’ve noticed these spiders on the house and garage, but too high up for me to get a good look, much less a picture. So when my husband came in the house and said he saw a red and brown spider on the cement by the remote garage, I headed right out. Almost trod on the poor wee girl.

Ok, so she’s not that wee. With her legs relaxed like in the shot above, she’s about the size of a quarter. Good sized, but nothing like the girls that live on the dock. She was very patient though and a great model, letting me get her best side!

On your mark

She’s an araneus marmoreus aka marbled orb weaver and according to my book, the females leave their webs up in small trees and bushes (or garages, you know, whatever works) and descend to the ground to lay their eggs. Judging by the somewhat deflated look of her abdomen, this female might have done that recently and is looking for a place to hole up for the winter. Or die. Many spiders die after only one mating season, but fortunately they leave the little ones behind as legacy.

No mercy

No mercy

Just look at the jaws on her! Orb weavers get their name from the shape of their webs – it’s that traditional round, net-like web that Charlotte wove in the famous book by E.B. White. This particular species usually stays out of sight under a leaf or similar shelter. She keeps at least one leg in contact with a special line of silk that, when the web is touched, will signal her that there’s something in it. Once the trap line is triggered and she springs from hiding onto the web, whatever is stuck there is lunch.

As you might have figured, all these images were made in natural light with the legacy Olympus 90mm macro with the 25mm extension tube. I hardly did any cropping! Seriously, she basically fills the screen when I focus down to nearly the closest distance I can work from.

Same with this bonus spider!

Xysticus ferox

So I was sitting on the deck when I heard a tiny *splat* and saw something land. It was this medium-sized crab spider. I picked it up to see if it survived and it was fine. I’m not sure if it fell from the roof, the trees or just the pot of flowers nearby. So I put it on the table where it immediately went to the underside. I flipped the table up and the light was lovely so I caught it and its little shadow. The ID is tentative. It looks like the female of this particular spider, but those pedipalps are giving me trouble. They look male to me. Ah, such is the joy of spider identification. 

 


Even tinier dudes in my yard

Last year we didn’t have furniture up on the deck except for a couple of plastic Adirondack chairs. With so many other things to do after the move, furniture was not a priority. But this year I bought a comfy couch and chairs so I end up spending more time up there. As a result I notice more and despite being really tiny, this little guy stood out –

It’s a burrower mayfly; easily identified by those big green eyeballs. The body, legs and wings are about 1/2 an inch long; the whole thing barely an inch. Here in Wisconsin we have many species of mayfly and some emerge in the hundreds of thousands; clouds so big they are captured on radar and mistaken for thunderstorms. It’s said that the massive presence of mayflies are an indication of clean water, so it’s good, but it has a downside. When they emerge en masse like that they leave behind their larvae carapaces which collect by the thousands along shorelines and docks. My shoreline. My dock. The smell was so bad that I couldn’t be outside until my husband pushed them all into the current and they were washed downstream (I tried to do it, but gagged and had to stop). I’ve come across a ripe moose carcass in the woods that smelled better. Unbelievable.

One at a time they’re pretty cool though. Mayflies are one of those species that exists for the larva stage. The adults have no mouths or other digestive organs and are basically just gonads with wings. And eyeballs. They live just days, mate and die. Their corpses are wispy, weightless things that float on the slightest breeze. I noticed several other kinds on the deck, but none were situated so nicely as this one – on my grill cover.

These next little bugs were on the deck railing just at the top of the stairs and because they herd together in a little group, they’re easy to see even though they are only about 3mm long (not including the feelers). The little stripes are so cute and so I had to grab the macro lens. I also used a 25mm extension tube so I could get even closer. They seemed to be eating the gunk that collects in the texture of the decking material. Because it’s not natural wood, I wasn’t concerned although if a bug that ate plastic did evolve, that would be a big help for us! Those two little balls in the lower right are what they look like – poop. Tiny, tiny poop.

After a bit of puzzling, an answer to what these guys are finally came from an insect ID group on Flickr.

The are Cerastipsocus venosus; commonly known as barklice or sometimes tree cattle which is hilarious because in one of my photo captions I mentioned how they herd together like cows and graze. The little group on my deck was only 10 individuals to start out with and I’m glad it wasn’t more because they do mass in the hundreds and that would have been kinda icky. A few at a time are cool though and here’s how they looked after a few days –

What I thought might be vestigial wings turned out to be just undeveloped and as they moved through the larval stage they got bigger and so did the antennae. The fully grown wings added another 2mm to the overall length, but the bodies didn’t grow. In the background of the shot up there, check out the orange spot. It’s visible to the naked eye, but I didn’t know what it was. When the critter sporting it got into a good position, I grabbed the camera again –

It’s a tiny mite; a parasite. Not sure if it’s harmful or not, but the bug itself didn’t seem to be the worse off for it. I love that you can still see the stripes through the wings.

Luckily when disturbed this little herd just froze up, allowing me to use natural light instead of having to resort to flash or very high ISO in order to keep things sharp. The last one has great light; the first rays of the rising sun. Even the tiniest creature throws a shadow.

So now I know what they are, will I be evicting them? Nope. They’re beneficial and non-destructive to wood or trees. Instead they eat fungi or algae or other organic stuff (gunk, yeah, that will do) that collects on tree bark and other things like my deck. I found some good info on this website.

 


Two tiny dudes in my yard

A while ago I posted about photographing birds in my yard and it taught me that I have a lot to learn about that kind of work. I’m MUCH more comfortable with small critters, so here’s a couple I found recently in the yard.

The first is a snapping turtle which I think had to be only a day or two old because

  1. it didn’t smell
  2. it didn’t have algae on it
  3. it wasn’t a crabby, bitey menace

Instead it was pretty mellow. Maybe the ‘tude takes a while to develop. Comes with size I would guess. Or the smell. I’ve seldom met big snappers who wouldn’t take your arm off given the chance. Sometimes I see really big ones in the river while I’m in the kayak. In my head I know they’re more afraid of me than I am of them, but they still give me the willies. Like one of them is going to come up out of the murk and bash my boat. This little guy though was pretty calm and easy to photograph. I put him in front of a log to use as a backdrop and got right down there with him. Everything about it has such terrific detail. It was only a couple of inches long. The only snapping turtle safe to handle; the ones that fit in the palm of your hand.

If you live anywhere but in the nitty-gritty urban city-scape, you’ve heard spring peepers filling the night with their mad song. It’s one of the things I look forward to most in spring; the first time I hear the peepers as the sun goes down. Weirdly though I’ve never actually seen one until the other day when one showed up on the deck.

I had to grab my field guide to figure out what it was. There is a bit of color variation in the species, but they have a distinctive X marking on their backs that nails the ID. I’m always amazed when I look at tiny creatures close up. If you enlarge the shot above you can see blood vessels in the arm on your right. The skin and bones are so delicate. Look at those wee toes! I thought it was pretty scared and backed off only to have it leap to the floor and give me enough time to change lenses for a more artsy shot –

It’s not even an inch long. How does something so small make such a big racket?

The toughest in the land

In northern Wisconsin we still get frost and freezing overnight temps well into May. What’s a demure beauty to do? Get tough. Spring beauty is one of the most hardy wildflowers we have and though it’s quite small and looks fragile, it survives almost anything Mother Nature can throw at it.

In addition to frigid temperatures, spring beauty can, and does, flourish in nutrient-depleted areas like housing developments and deforested areas like farms. It’s pretty undemanding.

Here in the yard though, there’s no skimping on soil nutrients, they grow in the lawn as well as in the woods where they have to push up through some very deep leaf litter.

They’re still blooming and I think I’ll have to go pick some because in addition to being adorable, they’re edible! The roots are actually tuberous, like potatoes, and it’s said they taste very similar, albeit sweeter and kind of chestnut-y so far as I could tell from info online. They can be eaten raw or cooked so I’ll have to get out there and get some while they’re at the peak of ripeness.
