Horsefly eggs

Word to the wise (from the not so wise): keep up on your photo archival! If you're a frequently active shooter, as I am, it's MUCH easier to amass lots of "keeper" images than it is to neatly label and archive them. Eventually all of my photos make their way into well organized folders, and I can lay hands on anything in seconds flat. But, over the past year, I have let some photo archival duties lapse, and am spending lots of time getting everything caught up - with dreams of not getting behind on this stuff again.

One perk of sorting through and labeling material from the year past is reminders of great field trips. On one of these - a foray to one of my favorite regions, Adams County, Ohio - from last September, I had taken a photo of "mystery" insect eggs. Hundreds of the off-white cylindric eggs were neatly arrayed into a fortlike pile, artful in its arrangement.

I knew who I could ask about their identity - Laura Hughes, who I have mentioned many times before on this blog. She quickly came back with an answer; an answer you may not necessarily be pleased to hear.

Horsefly eggs!

While these brutish biters are not everyone's cup of tea, I've always liked horseflies, in part because of some species' wild op-art technicolor eyes.

A horsefly in the genus Tabanus, perched atop my car and ready to attack. I made this image in Erie County, Ohio back in 2013. Note the crazy eyes. I've been known to take bites in order to get photos, as HERE. And I'll take more bloody rasping bites for the team, I'm sure, in order to get ever better photos of the fantastic eyes of these amazing creatures.

Who, as it turns out, also have amazing eggs.

Two amphibians: One bold, the other bashful

My recent forays into the depths of southern Ohio have produced many interesting animals, including the two that follow.

Before we get to the goodies, ever wondered why horsefly bites hurt so much? We captured this large specimen, presumably in the genus Tabanus, and made some photos of its piercing and sucking parts. Take a gander at the dagger of a proboscis stuck to its face! That's what it jabs into your flesh and rasps you with until you bleed. Small wonder that these little pests even send large horses into conniptions. I made a post with more detail about these six-legged tormentors HERE, should you want to know more.

Aha! An orange salamander, boldly traipsing about the forest floor in broad daylight. It could only be a red eft, the larval form of the red-spotted newt, Notopthalmus viridescens.

Red efts are fearless, to wax unabashedly anthropomorphic, because they are poisonous. Highly poisonous.

Fillet of fenny snake,

In the caldron boil and bake;
Eye of newt, and toe of frog,
Wool of bat, and tongue of dog,
Adders' fork, and blind-worms sting,
Lizards's leg, and howlet's wing,
For a charm of powerful trouble,
Like a hell-broth boil and bubble.

Excerpted from Macbeth, by William Shakespeare. Bill was onto something, by having his witches cast newt eyes into their foul broth. Newt or eft parts would certainly add a potent dash of tetrodotoxin, the toxic chemical that protects these little salamanders from evil-doers.

This amphibian, contrary to the eft, hides very well and its coloration is quite the contrast to an orange salamander.

Gray treefrogs, Hyla versicolor, are chameleonlike and can change color to blend with their surroundings. This one is stuck to a tulip tree, and it meshes well with the grayish bark of the trunk.

Here's a gray treefrog - same species - that we had found a few days earlier. Its coloration is a jarring contrast to the drab gray hues of the animal in the preceding photo. This one was spending time on leafy material, and wisely shifted over to matching shades of green.

Those eyes

While strolling a woodland path recently, I couldn't but help to notice some horseflies in the genus Tabanus. Occasionally one would swirl around and attempt to bite one of my appendages but for the most part, the flies that I saw were laying low, perched on the dirt path.

Most people probably never bother to stop and take a CLOSE look at one of these creatures. They're too busy swatting and flailing about in an attempt to get the bug to leave them alone. Can't say I blame 'em; the saw-toothed proboscis of one of these biters HURTS as it rasps its way into your bloodstream. But there is one feature of the horsefly - many other flies for that matter - that is undeniably cool but seldom seen.

Their eyes.

So, to bring you the rest of the story, I got down in the dirt with the fly above, who was amazingly cooperative, and rammed the macro lens into its face.
