Sweat Bee

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.

Diabrotica undecimpunctata (Spotted Cucumber Beetle)

I went on a short outing this afternoon to the Agricultural Farm Park today and spent a little time wandering around the Master Gardener’s display garden. Mostly I photographed insects (and a few flowers). It was a pretty productive outing as far as insect photos go.

  • Danaus plexippus (Monarch) Caterpillar
  • Murgantia histrionica (Harlequin Bug)
  • Papilio polyxenes asterius (Black Swallowtail)
  • Euptoieta claudia (Variegated Fritillary)
  • Allograpta obliqua (Common Oblique Syrphid)
  • Diabrotica undecimpunctata (Spotted Cucumber Beetle)

I’m particularly happy with the oblique syrphid fly, as that’s the first one I’ve photographed. The black swallowtail is one we don’t see nearly as often as the eastern tiger swallowtail. I’ve seen harlequin bugs on occasion but not all that often. The same is true of the cucumber beetle.

Carpenter Ant (Camponotus castaneus)

Carpenter Ant (Camponotus castaneus)

I came across this carpenter ant (Camponotus castaneus) in the yard today. I wasn’t sure I’d be able to get an identification on this ant. BugGuide.net says, about carpenter ants (Genus Camponotus), “This is one of the most species-rich ant genera, with perhaps 1000 species World-wide.” Nevertheless, it was identified. These are pests, of course, if they get into structures or valuable trees but they are fairly ubiquitous on almost the entire globe (only excluding the polar regions). They’re pretty things, like most insects, however.

Bombus impatiens (Common Eastern Bumble Bee)

Who doesn’t love the humble bumble bee? They are everywhere and like many of us, they are not particularly flashy or flamboyant. Nevertheless, they busily go about their business. I like them quite a bit and enjoy watching them move from flower to flower. In this case, a common eastern bumble bee (Bombus impatiens) is on wingstem, also known as yellow ironweed (Verbesina alternifolia). There were also honey bees (Apis mellifera) and ailanthus webworm moths (Atteva aurea) on the same group of flowers. It had become quite hot again, with temperatures in the low 90s, and I’m starting to look forward to autumn.

Paper Wasp

Paper Wasp

Paper Wasp

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”).

Eumenes fraternus (Potter Wasp)

Eumenes fraternus (Potter Wasp)

Eumenes fraternus (Potter Wasp)

This potter wasp (Eumenes fraternus) is one of my favorite wasps (doesn’t everyone have favorite wasps?). There’s fairly common around here. While they are particularly drawn to the mountain mint (Pycnanthemum muticum), they are also found regularly on the black-eyed Susans (Rudbekia) and painter’s palette (a.k.a. knotweed, Persicaria virginiana). I think it’s their clean lines that I like. They’re difficult to photograph well and I’m not really happy with this photo, although it’s the best I was able to get. They don’t really stop moving and unless the light is very strong, it’s hard to get both adequate depth of field and a short enough exposure to stop their motion.

Sphex nudus (Katydid Wasp)

Sphex nudus (Katydid Wasp)

Sphex nudus (Katydid Wasp)

The bees and wasps are out in force these days. I spent a little time around the mountain mint (Pycnanthemum muticum) this afternoon and enjoyed the variety of buzzing insects (most of them are basically silent, actually). The most numerous are the bumble bees (Bombus impatiens) and the large but gentle carpenter bees (Xylocopa virginica). The wasps are pretty well represented, though, and today I saw a handful of these katydid wasps (Sphex nudus) as well as some potter wasps (Eumenes fraternus). I got a few photos of that last one, but they weren’t as good as I would have liked. I’ll keep trying.

Dolichovespula maculata (Bald-faced Hornet)

Dolichovespula maculata (Bald-faced Hornet)

Dolichovespula maculata (Bald-faced Hornet)

The pollinators are quite busy in the yard these days. Especially in the afternoon, when the sun is hammering down on the flowers, the bees, wasps, moths, and butterflies are to be seen in great numbers. The mountain mint (Pycnanthemum muticum) is literally a buzz with them. The skippers seem to favor the black-eyed Susans. The butterflies, not surprisingly, go for the butterfly bush (Buddleia). That being said, this large hornet was coming back again and again to the buddleia. I’m not as happy with it as I might be but it’s a decent photo. These wasps are social and build large paper enclosed nests. I’m a little surprised to only see one of them, but there are surely more around the area.

Western Honey Bee (Apis mellifera)

Western Honey Bee (Apis mellifera)

We had another day at Shady Grove Hospital today but before I went I took a few pictures in the back yard. There was a monarch butterfly (Danaus plexippus) on the butterfly weed (Asclepias tuberosa) and I had hoped to get a picture of that. I would have, except I had taken the memory card out of the camera and when I put it back in the write protection switch had been pushed into the off position and the camera would not take a picture. By the time I got it reset the butterfly was gone. I was able to get this photo of a western honey bee (Apis mellifera), instead.

Megachile mendica (Flat-tailed Leaf-cutter Bee)

I have yet another “insect on a black-eyed Susan” photo today. These are by far the most numerous flowers in our yard this time of year. They aren’t necessarily the insects’ favorite flower but most pollinators are fairly broad minded and visit lots of different plants. The Buddleia bushes are the clear favorites with the butterflies and the mountain mint (Pycnanthemum muticum) is probably the most popular with the bees and wasps, but they all visit the black-eyed Susans, as well.

Eastern Bumble Bee

Common Eastern Bumble Bee (Bombus impatiens)

Common Eastern Bumble Bee (Bombus impatiens)

I went out looking for pictures as usual this afternoon, when I got home from work. There is Campanula in bloom in the yard, and I took some pictures of those flowers. They don’t tend to come out the same color in photographs as they are in real life. Not entirely sure why. Then I moved over to the gooseneck loosestrife (Lysimachia clethroides), which is a real attraction to the bees. It’s quite invasive and I really would recommend against planting it in the strongest language, but if you already have it, you might as well enjoy the bees. There were a few honey bees but mostly it was the common eastern bumble bees (Bombus impatiens) that were moving quickly from flower to flower.

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.

Monarch and Bumblebee

Monarch and Bumblebee

I know I posted a photo of a monarch butterfly (Danaus plexippus) recently but I sort of like this photo of a monarch sharing a coneflower (Echinacea purpurea) with an eastern bumblebee (Bombus impatiens), so here you are. This was taken in the same garden as the former and like that one it was in the afternoon when the shade of the building was on it, so it isn’t as well lit as I would like.

I walked around the small pond next to my building and saw lots of raccoon footprints in the fresh mud. I took some pictures of those and also of some skippers, a cabbage white (Pieris rapae) and a pearl crescent (Phyciodes tharos).

Eastern Carpenter Bee (Xylocopa virginica)

Eastern Carpenter Bee (Xylocopa virginica)

Eastern Carpenter Bee (Xylocopa virginica)

Cathy called me around the south end of the house late this afternoon to take pictures of this male carpenter bee (Xylocopa virginica) on the buddleia growing there. Carpenter bees are nice to photograph because they don’t mind you getting fairly close to them. Also, the males like this one, identified by the white or pale yellow patch on their face, don’t sting and in fact are unable to do so. I don’t find many bees to be particularly aggressive, though, and I know some people are quite afraid of them. For me, as long as I move slowly and carefully, I’ve never had a problem. I’m not particularly allergic, either, which is important.

Potter Wasp

There were lots of insects enjoying Cathy’s mountain mint (Pycnanthemum muticum) today, including this potter wasp. I’ve narrowed it down to the genus Euodynerus of which there are 19 local species. Beyond that, I need better pictures and different views.

There is a good key to the genus here: http://www.biology.ualberta.ca/bsc/ejournal/bmc_05/key_euodynerus.html. I also found a good Hymenoptera glossary here: http://www.diapriid.org/projects/32/public/ontology/.

I’ll end the first six months of Project 365 with a honey bee (Apis mellifera), busily visiting the flowers on a wild onion in the empty lot next to my office.

I went out hoping to get a better butterfly picture today. I got a few but they aren’t enough better than yesterday’s picture to justify putting them here. So, here’s a picture of a yellow jacket on a garlic mustard flower.
