July 10 Photos

Dogwood Spittlebug (Clastoptera proteus)

We were expecting the remnant of a hurricane today so Lucy and I needed to get outside for bugs a bit earlier than usual. As it was, it began raining only 30 minutes into our time outside, but we managed to find some nifty bugs. 

Above, is the cutest ever dogwood spittlebug. It's almost invisible. You may see a black or yellow pencil dot moving on a leaf (not necessarily on a dogwood leaf, either). This was only my second sighting of one and it was quite larger than the first. I can't find out whether the broad yellow strokes on it are developing wings or just the way they are decorated. I hope you click on the photo to see it larger. It is worth the time to completely read all sections of  "Spittlebugs and Froghoppers." 

Globetail fly (Genus Sphaerophoria)

Above is a globetail flower fly (also called hoverflies or syrphids) . They are very important for pollination, as are nearly all of the flies. These flies are much bigger (although still very small) than the Toxomerus species of flower flies, one of which is below. 

Margined Calligrapher (Toxomerus marginatus)

This margined calligrapher flower fly was in the rugosa rose bush pollinating away. Hopefully, you are able to discern how small they are. When they fly, they are just wisps in the breeze. There haven't been too many so far this season. Their activity seems to be strongly affected by the time of day and the air temperature.

I try to photograph as many Japanese beetles as possible to see if they are carrying a winsome fly egg . . . but viewing the photo in the iPad, I found this small crab spider instead! It was a great find. If the spider caught that beetle, it would be food enough for many days.

It has been a long, long time that I seriously posted. Many things have stood in my way: school work, disabilities, Covid (but it was uneventful for me), the flu, and myself. I get in the way of myself all the time. 

I am in the middle of learning and planning an entire year of science classes (K-12) that meet the NGSS standards. In November of 2023, I was given all the science classes of the school because the science teacher quit. I had two weeks to formulate plans to last us until the end of the year. I did it but was never that happy with the results. I have told the school's director that I will happily continue in science. That means they need a new math teacher, but we have made changes to the math curriculum, legally and beneficially, that takes most of the pressure off of filling that position. It's fun teaching science. Not so much math, though. After 30+ years of teaching math, it is now too rote for me.

There are no math teachers to be found, anyhow. The entire state is looking for them. There seem to be no teachers anymore. I have no idea why. But every Vermont school is short, drastically short of teachers. 

I have changed my workflow for photos. I use my big iPad and the Apple photo app and find that they are as good, and sometimes better, than my big desktop with Adobe Lightroom. I still use my Canon camera but use wifi to transfer photos to the iPad. I can then geo tag and upload the shots to iNaturalist easily. And then I also make a memory video slideshow of the best of the day (that doesn't mean the best photos, just the best shots of the day). And that video I send off to family, who probably roll their eyes at them. I'm having fun seeing what limits I have on creating my own video memory videos on my devices. This is today's:

Arachtober: Goldenrod Crab Spiders

Goldenrod Crab Spider (Misumena vatia) and
Mining Bee (Genus Andrena)

You'll find these beautiful spiders across the US and southern Canada. If you haven't seen any, you are missing something of beauty. They can actually change their color from yellow to white and back. However, it takes an entire month to do that, and in Vermont summer is gone in a month. Almost. They may or may not have the red stripes. They also may be green or have pink. There is another flower crab spider that is so similar to this species that I try my best to photograph the eyes. The placement of the eyes is the determining field mark for me.

Mining Bee (Genus Andrena)

These spiders don't make a web. They are hunter spiders, so they jump at prey when it comes close. They do have draglines, though, which you may see in these photographs if you look at them in the large format by clicking. The goldenrod crab spins silk to hold her eggs. She will then fold a leaf around the eggs (which is one reason why I gave that entomologist such a hard time about the identification of the candy-striped spider with all the webbing). Funny thing, though: I've never found eggs. I have to look harder. This is a female spider in the photos because the males are brown and are very small. Mother spider stays with her eggs until they hatch. Then she dies. But she may live for at least two years, which I find heartening amongst all of the short lives of other insects.

There are so many different flower crab spiders; from this large goldenrod crab on black-eyed susan, to tiny little green or white ones on fleabane or oxeye daisies. It seems that the smaller they are, the quicker they run, so tread quietly and don't cast a shadow on them if you want to see them. All of them will go under the flower petal that they are hunting on if they are aware of you. The goldenrod crab will eat anything that moves: even another goldenrod crab spider! Unfortunately, it had caught this miner bee. It was not the nicest thing to watch, but it is what life is.

The reason why researchers are trying to learn if candy-striped spiders are impacting pollinators in North America is for this very reason. Before them, there was a healthy balance of spiders and pollinators. With the candy-striped spider, it is possible that the balance could skew towards the spider. We need to know what is going on. Your observations will help researchers find an answer.
