Bees

We’ve had a lot of wasps on here recently, so how about a sampling of bees now? Great Northern and Brown-belted bumblebees.
One of the leaf-cutters. Megachile genus bees carry pollen on their abdomen.
Eight-toothed Cuckoo Leaf-cutter.
Agapostemon genus.
Confusing Furrow Bee. Maybe.
Two-spotted Longhorn.
Is this a drop of water or nectar? Either way, this bee’s very long tongue was shooting through it over and over, lapping it up. I guess…

Raptor Wednesday

I could hear this Red-tailed Hawk youngster calling from some distance away.

Butterflies

Red Admiral.
Orange Sulphur.
Clouded Sulphur.
Black Swallowtail.
Spicebush Swallowtail.
Eastern Tiger Swallowtail.
Question Mark.
Red Hairstreak.
Fiery Skipper (male).
Eastern Tailed-blue.
Summer Azure.
Sachem (female left, male right).

Butternuts

The tropical storm with all the vowels in its name brought down a lots of branches in the city last week. Green-Wood Cemetery was closed for two days for clean up. Some whole trees were uprooted as well, and some weakened ones snapped.

One was this butternut, Juglans cinerea. Already a shadow of its former self — that’s the pre-storm stump there on the right — it’s definitely taken a powder now.
Just look at this leaf! My boot is about a foot long.
Elsewhere in the cemetery: this sapling, which looks like hell.
I don’t know what this crud is. Let me know if you know. The butternut canker fungal disease, which has killed approximately 80% of the butternuts in their native range (eastern North America) doesn’t, as far, as I can tell, hit the leaves. Again, correct me if I’m wrong.
Here, at least, is one fine specimen.
The nuts, which which are supposed to be delicious, mature earlier than our native black walnuts (Juglans nigra).
These aren’t very oblong, are they? The fruits are supposed to ridged, too. So could this tree mislabeled? Or is it some kind of hybrid with black walnut? (The husks have a wonderful lemony odor, btw; but watch out: it has been used as a dye and can stain your skin.)
The sound of gnawing and husk-fall could be heard before I spotted a couple of squirrels up in the branches munching away.

Book and Flowers and Bugs

A month of summer yet, at least as the calendar goes. But Carol Gracie’s Summer Wildflowers is good the whole year through. You’ll love opening this in early January!

I can’t better the foreword by NYBG’s Robert Naczi: “Gracie seamlessly integrates diverse facets about these plants—history, geography, habitats, human uses, morphology, classification, pollination, conservation, and more. Truly, this book has something for everyone, whether beginner or expert,hikeror gardener, entomologist or etymologist.”

In honor of Carol, who reads this blog (!), here are some interactions with common milkweed, Asclepias syriaca. (If you’ve ever wondered why the species epithet means, essentially, “of Syria,” she explains the chain of errors that resulted in that.)
A tiny bee. Perhaps a sweat bee.
Nomada genus bee.
Scirtes orbiculatus, a marsh beetle.
Monarch egg.
That’s a honeybee on the left. I was trying to capture in pixels the pale ant here, but this is a bonus since it shows a yellow pollinarium, the two connected pollen sacs, or pollinia, that milkweed sticks to you in exchange for giving up its nectar.
Bembix genus sand wasp.
Great Golden Digger wasp.
And right next to this patch of milkweed in Green-Wood, a Great Golden Digger digs her nest site. While she sups on nectar, she provisions her young with crickets and katydids.

Mourning Dove

Blue-winged Ones

Zethus spinipes, I think. One of the potter and mason wasps. Note all the parts of the mouth, like little tendrils.
Isodontia philadelphica, a grass-carving wasps, also sans a common name.
Female and, with the face dot, male Four-toothed Mason Wasps (Monobia quadridens).
Nearctic Blue Mud-dauber (Chalybion californicum), presumably. Very similar looking to the Steel-blue Cricket-hunter Wasp (Chlorion aerarium).

Sharpshooters


A nymph Broad-headed Sharpshooter.

The adult form is amazing, so I’ll keep my eye out for them now. A lot of people resist the appeal of insects, but this one might break down some barriers.

In unmown meadow, here’s a Draeculacephala genus sharpshooter. Couldn’t get another photo because it shot off at the slightest provocation.

Sharpshooters are true bugs, in the leafhopper family family (Cicadellidae). I’m used to much smaller leafhoppers, just 3-4mm, and a struggle to photograph alive. These two sharpshooters were closer to a centimeter long.

Raptor Wednesday With Gliders


Two American Kestrel males in Green-Wood.

Hunting must be good here, because I’ve seen kestrels in this area for years. There are some great perches, with meadow below. When I was there Saturday, both Spot-winged and Wandering Gliders, the orange-y dragonflies that seem to be constantly in the air, were flying at eye-level. Kestrels eat dragonflies. Crunchy on the outside, gooey on the inside — one supposes.

Rare to see a Wandering Glider perched. They’re on the wing most of the time. The Flying Dutchman of dragonflies.
Spot-winged Glider. They don’t perch much either, but perhaps a little bit more than the Wandering. Fairly similar, but with small dark patches at the hindwing base.
These smudges can be seen in flight…

Cicada-Killers

It’s time to suck the lilac sap again.
How does one tell individual insects apart? Well, look at the abdomen patterns on these Cicada Killer Wasps. There are subtle distinctions between individual females as well as between individual males.
And then there’s sexual dimorphism. The male is rather smaller.
Females are big and burly for a reason: they need to fly while holding paralyzed cicadas for their young. Dog day cicadas run close to 2″ long including their wings.
Here’s a female emerging from her burrow of a nest, amidst the freshly excavated dirt.
