I met Cathy outside for a little while early this afternoon. As we were walking back towards the entrance to my building we saw a white-tailed deer (Odocoileus virginianus) near the parking lot and I was able to get a few nice photographs of her. Cathy went back to her office and I went down near the pond and took some photos of insects. There was a type of fly that I hadn’t seen before. I thought it was a thick-headed fly (Family Conopidae) but it was identified as a Dioprosopa clavata, a syrphid fly (Family Halictidae) that resembles a thick-headed fly. Today’s photo, however, is of this metalic green sweat bee, a female in the genus Augochlorella.

I took pictures of insects on aster flowers this evening. There was a bumble bee covered with little white dots that I’m pretty sure were eggs of some kind and didn’t bode well for the little critter. There was also a beautiful, metallic green, sweat bee (family Halictidae) and I got a picture of it as it lifted off the flower, which would have been amazing if it had been in better focus. The light was relatively low and I was using a flash with a white reflector for these pictures, which helped considerably. I also had a 25mm extension tube behind my 100mm macro lens, which helped me get that much closer.
I was out photographing flowers this evening. The light was fading and I didn’t think I could realistically get any photos of bees, wasps, or other flying insects. I was down on the ground to get some pictures of obedient plant, Physostegia virginiana, and I happened to notice this little fellow. I went in and got my flash, so I could get pictures that were worth something and I’m pretty happy with the results. This little bug (a true bug in the Heteroptera suborder) is only two or three millimeters long and if I hadn’t been down on the ground and very close, I never would have seen it. It is a twice-stabbed stink bug, Cosmopepla lintneriana. This one happens to be a nymph (an immature) and when adult will be mostly black with two red patches (the two “stab” marks of its common name).
There are a few paper wasps that are very difficult to distinguish and some that are impossible without examining them at the microscopic level. A number of them are quite variable, as well, adding to the difficulty. I think this is a northern paper wasp (Polistes fuscatus) but I’m nowhere near sure. It’s a beautiful creature, whatever it is. This was taken with my 100mm lens with the addition of a 25mm extension tube in bright evening sunlight. As you can see, I was able to get fairly close and I’m pleased by how sharp this turned out. You might also notice the aphids on the underside of the leaf the wasp is on. I took some photos of those, as well, but haven’t identified them yet (beyond the generic “aphid”).
I took a few pictures of butterfly weed flowers this evening and I might have posted one of them. A little later I noticed this white leafhopper and got a few pictures of it, including this reasonably sharp image. Getting a good picture was made more difficult by the breeze, which was moving the stem the planthopper was on, but this one turned out pretty well. It was sharp enough for it to be identified as a northern flatid planthopper (Flatormenis proxima), one of our more common planthoppers. They do little damage and I left him alone to get what he needed from this plant.
I took some pictures of flowers and plants in the back yard this evening. I had gotten down onto the ground to see if I could get a good picture of a syrphid fly on an allium flower. I got a few pictures but they weren’t as sharp as I would have liked. Then I noticed this ant on another allium and got a handful of pictures of it. They aren’t all that sharp, either, but will have to do, because I didn’t really get anything better. I’m pretty happy with the framing of this picture and the exposure, but the focus isn’t that great. In my defense, this little fellow was moving around quite a bit and the light was starting to wane a little.
We’re moving from the flowers-of-spring period into the insects-of-summer. Along with the insects come those creatures that prey on them, most notably the spiders and related creatures. Of course, birds, bats, and even other insects prey on insects, but I have a special fascination with spiders. They are not, I am led to believe, universally admired. I suppose I understand that. Nevertheless, I think they are quite beautiful, at least some of them are. This is Leucauge venusta, the orchard orbweaver, and a common resident in our area. It’s so delicate and looks like it could be made of glass. It’s been said that you are never more then six feet from a spider. Even if that’s not literally true, it’s probably mostly true. Sleep well.
We have two Kalanchoe plants. This one is Kalanchoe daigremontiana (a.k.a. Bryophyllum daigremontianum) and it’s a pretty little thing, although our plant isn’t particularly robust. Most of our house plants have been somewhat neglected lately. We have lots of excuses, such as the disruption from the renovation project, Solomon’s cage (and Solomon, of course) being moved in front of some of them, or the fact that it’s winter and some of them do better outdoors, during the summer. I do try to get at least a little watering done now and then and we have a small mint next to the kitchen sink. When it starts to wilt, I know it’s watering time.
I took my camera with me to a meeting across campus and then spent a little time taking pictures on the way back. The Amur honeysuckle (Lonicera maackii) is starting to leaf out and in spite of the fact that it’s quite likely that we’ll have another freeze, it’s not at all bothered. It’s pretty well suited for cold and a light freeze or two isn’t going to do it any harm. This little insect, however, may be jumping the gun a bit. I don’t know, really. Perhaps it, too, has ways to deal with late freezes. I know some of my followers think it a bit funny that I try to identify all the plants and animals in my posts with their Latin names. You’ll be happy to know that I have no idea what sort of insect this is and I’m going to leave it at that.
As we’ve been going through things at Cathy’s parents’ house, there has been, as there would in any house lived in for 50 years, an accumulation of things that don’t need to be kept. Some of them are just trash that got mixed in with other things. Some are things that were once important but the importance has worn off or the timeliness has passed. There are, of course, things of value, either sentimental value or intrinsic monetary value. And, of course, there are curiosities. David found two little slide mount size holders with sets of miniature US coins. Shown here with a regular quarter and penny for scale are (clockwise from center top), Kennedy half dollar, Jefferson nickel, Roosevelt dime, Eisenhower dollar, Lincoln penny, and Washington quarter.
The skippers are out in force these days. I got one picture with three of them on a single bunch of flowers. They move around a lot, making it a little harder to get a good picture but there are so many of them you can almost pick a flower and wait for one to land on it. They are somewhat plain as butterflies go. The butterflies and skippers are grouped together in the superfamily Papilionoidea under the order Lepidoptera. The other superfamilies (there are quite a few) are all moths.
After taking the picture of the lady beetle larva in the woods, I crossed the stream on a fallen tree trunk. I worked my way from there through a fairly dense area of brambles and small trees to the slope that leads to what I call the uplands part of the empty lot. This is about 30 feet higher than the lowlands across the stream and it is mostly clear of trees. It is filled with ragweed and milkweed with a few empty spots that are almost barren, with just bare clay which sometimes holds standing water and other times is baked into a cracked, hard surface. In one of those empty spots, I followed this wasp, which is Cerceris fumipennis, an apoid wasp (Apoidea) in the family Crabronidae. It landed and disappeared into this little hole in the ground. I figured it would eventually come out again so I got down and waited. I was rewarded for my patience when he appeared at the entrance and was able to get a half dozen shots off before he flew off into the distance.
It was a beautiful, if somewhat hot afternoon today and I went out into the woods next to my building. As I walked through the underbrush under the sycamore, tulip poplar, redbud, walnut, and black cherry trees, I noticed this little creature on a leaf. This is the larva of a lady beetle. The family Coccinellidae, the lady beetles, has about 6,000 species in 360 genera worldwide and nearly 500 in eastern North America. I have no idea to which of those this larva belongs and I’m not even going to try to figure it out. The adults are generally easier to narrow down but to me, anyway, the larva are just too much alike. I found a key to the larva of North American lady beetles but it starts out as follows. Tell me how helpful this is to you:
Mandible with digitiform teeth, retinaculum absent; terga with scoli, sometimes with parascoli; frontoclypeal suture complete; antenna long, 3 or more times as long as wide, of nearly uniform diameter.
It was a slightly less warm but every bit as humid day today. I went to eat my lunch in the empty lot next to my building, sitting on the edge of a now-dry drainage pond. This pond rarely has more than a few inches of water in it but the water is gone and the mud has cracked and is only damp. I had expected to see more insects there but I suppose it’s dry enough that even they have moved to somewhere with a bit more water. I took some pictures of the flowers of some softstem bulrush (Schoenoplectus tabernaemontani) and this Japanese beetle (Popillia japonica) came and landed right in front of me. I was able to get four quick shots before it flew away. In this, the last of the four, its wings are just starting to open.
I went out to take some pictures of flowers this afternoon and that’s what I did at first. Well, first I got a few pictures of a rabbit (an eastern cottontail, Sylvilagus floridanus). Then I took a few flower pictures but I noticed this little fellow on a coneflower (Echinacea purpurea). It is the nymph of a Scudderia, a genus of eight species in our area comprising the bush katydids. This is just a small portion of the larger group of all katydids, of which there are nearly 250 species in 49 genera in eastern North America. Anyway, I think this is a cute little guy and I took quite a few pictures. Enjoy.
I know many of my followers are less than thrilled with my spider photos. Nevertheless, at the risk of chasing off either of them (my followers, that is), I’m going to post another. I went for a short walk early this afternoon. There is a section of the road behind my building that has a well along the sidewalk, above a stream. Growing on that wall are Virginia creeper (Parthenocissus quinquefolia), wild grape (Vitis species), porcelain berry (Ampelopsis glandulosa), and of course, the ever present poison ivy, (Toxicodendron radicans). I stopped to take a few pictures of bumble bees on the Virginia creeper flowers and then noticed this little jumping spider on the underside a leaf. Kind of cute, I think.
I was out in the yard taking pictures this evening and after taking a few of the rose I just posted, I noticed that there were a lot of little insects moving around in the grass. When I say little, I’m talking about insects in the 2 to 3mm range. As I walked around, they leapt away from me. I got down on the ground but when they were not moving, they were hard to find. What I did find, however, was this exuviae, the exoskeleton of some small insect that left it behind on a blade of grass. It’s about 5mm long and appears to be from some sort of grasshopper or cricket. The word exuviae is Latin and means ‘things stripped from a body.’
I don’t know that I’d call this a serious pest but it certainly does make our garden look worse this time of year. This little bug has been here in pretty good numbers in recent years and they suck the juices out of some of our plants, making their leaves brown and desiccated. It generally doesn’t do the plant irreparable harm but it doesn’t do it much good, either. In past years I spray them and cut them off before they do their worst. This year I never got around to it and the damage is pretty well done at this point. They’re pretty, little things, I admit. But pests, nonetheless.
