This guy lives up to the name--it's the most frequently seen dragonfly in the yard. This is a male, with his bluish white abdomen; females are the same shape but have brown "tails" marked with light diagonal dashes. (As seen here.) All dragonflies are predators that catch other insects in flight, including biting flies. You should always be happy to have dragonflies around.

New England's biggest dragonfly is also one of the most common. This female green darner Anax junius* rested briefly in our yard--later we went to the beach and we saw many of them flying around the shore. They are famously migratory, hunting as they go, covering 30 miles a day. Because the ones that appear in spring have little to no wing damage, it is thought that each year a new crop migrates each year. Slightly more battered darners head south when insects become scarce in the fall.

We see these in the yard on a regular basis throughout the summer. My first instinct is, well, clearly that's a 12-spotted something or other. But since dragonflies tend to be named for the flashy males, distinctive females like this one end up with nonsensical names. This is the female of the common whitetail Libellula lydia*, named for the male's frosty blue-white abdomen. Like the meadowhawks discussed earlier, this species wanders from from the water (where they spend their larval days) to hunt in fields and forest edges, and the suburbs that approximate such habitats.

* This name is not accepted by all (notably bugguide) but seems to rule the day on wikipedia at least. "Libellula" is coined in scientific Latin from libella, which itself refers to a very small coin. What the hell does that have to do with anything? Beats me, but was more than I could find out than I could about "lydia," which seems to always have been a woman's name, derived from the name of an ancient land in present-day Turkey.

Alexis is my go-to dragonfly identifier. She's studied the book, and has a good grasp of where to look on these things to tell them apart from one another. She was able to tell at a glance that this was probably a young male meadowhawk. Meadowhawks (genus Sympetrum*) are smallish dragons that are often found in fields (and suburban yards) far from water. Adult males are bright red, but females and young males are less colorful.

She was able to determine very quickly that this was one of the meadowhawks that represents a trio of species that are nearly impossible to tell apart, without a dissecting microscope aimed at their ... abdominal appendages. There is some thought that at least two of the three species are only one species previously described as two. We will content ourselves by saying that this is either Sympetrum internum**, S. obtrusa***, or S. rubicundulum****.



* "With rock" possibly referring to being found in habitats far from water
** "Interior" -- an anatomical descriptor?
*** "Sticking out" probably a reference to the white face of the adult male of this species
**** "Miniature ruby"

Stone Zoo has an American alligator exhibit open for the summer! There are three medium sized gators in there; keepers go in teams to clean it, with one zookeeper in charge of making sure the animals keep their distance.

I was at Stone Zoo to (among other things) set up stable fly traps. This dragonfly unwisely landed on my pile of sticky sleeves--fortunately the backings are still on them, so the odonate was not trapped.

On Sunday, Alexis and I took Charlie and Albee to Turtle Pond. It was pretty warm but not as hot as it has been earlier in the summer. The Pond had many bathers in attendance, some of whom appear to be riding Charlie's head.

Meadowhawk Sympetrum sp.

Meadowhawks are small dragonflies that often hunt far from water. In many species the males are red. Determining species often can only be accomplished by closely examining the terminal appendages of the male--not yet a hobby of mine. This one was perched on a plantain flower/fruit stalk long enough for Alexis to suggest I go get my insect net and catch it. This is the way to hold a dragonfly (in zookeeper talk: manually restrain) so that you don't hurt it and it doesn't get away.

I've noticed that after some manual restraint many insects are tired, and rest a while in place before flying away.

Our July Urban Nature Walk took place in the small city of Quincy, where there was some known habitat of a particular very special species of wasp. My friend Jenn, an invasive species expert with the State Department of Agriculture led a small group of us behind a big indoor skating rink to a barely maintained little league field called Curry Field

This past Sunday we had an Urban Nature Walk in the Bussey Brook Meadow Urban Wild. This little chunk of land connects the Forest Hills rapid transit stop to the Arnold Arboretum, making it very easy for any car-free Bostonian to get there. As it happens, two of us came by car, two by bicycle. This photo is from the end of the walk, when we emerged from an Arboretum gate to find an abundance of black raspberries!

This female common whitetail Plathemis lydia was resting on the fence of our little yard.

There is a swampy area a few hundred feet from our house, and Turtle Pond and Stony Brook are not far down the road. Still we were surprised--but gratified--to see dragonflies hunting in the yard. Dragonflies are active predators, catching other insects in flight. Male common whitetails have fat bluish-white abdomens, but as when this animal was 100 urban species #32, I have photographed the less distinctive female. Spots on the wings caused me to misidentify it as a 12 spotted skimmer, despite having seen the species before.

Common whitetail Plathemis lydia

The common whitetail is named for the male's pale bluish-white abdomen. The female looks very different, with a dark brown abdomen marked with light colored diagonal dashes. The male of this dragonfly species are unmistakable, but at least one guide warns that the female's dark wing markings make her resemble the 12 spotted skimmer. The 12 spot has a much longer abdomen with a more slender overall appearance. The whitetail also has a habit of perching on the ground, a behavior less likely in the other dragonfly. Alexis and I photographed these female whitetails on two consecutive days, perching horizontally on the stone footbridge in the Riverway. When disturbed they would fly a short distance away, landing horizontally again, or vertically as shown above, on a nearby tree. We took these animals to be resting at the end of their life spans, but they may live on for a few more months, feeding on mosquitoes, midges, and other flying insects by the river.

Widow Skimmer Dragonfly Libellula luctuosa

Dragonflies breed near water, and their nymphs live there, feeding on mosquito larvae and other aquatic insects, and the adults are most often found within a short distance of ponds or lakes. Widow skimmers, like this female photographed in Franklin Park, a mile or so from the nearest significant body of water, will fly to far off fields to hunt insects. Male dragonflies of most species engage in battles to defend the territory where their mates have laid eggs. Not so the widow skimmer, thus the colorful name. The animals themselves are colorful and show sexual dimorphism: the female has these distinctive yellow stripes, while the male is bluish with unique white and black markings on its wings.

So it was so warm we decided to walk to Ward's Pond and let Charlie have a swim. It was very windy and here Alexis is surrounded by blowing leaves.

We went to Lost Pond Reservation again today, and I collected some more mushrooms for spore prints, including this lovely Russula (or one just like it).

I recently got a new lens for the new camera. It's a Sigma 28-80AF zoom with macro focusing ability. I haven't taken any really good Muddy River pics with it, so I thought I'd experiment with it on yesterday's walk at the Lost Pond Reservation. Pokeberries are fruiting, so my first picture was a shameless steal from one of Alexis' recent pictures.
