Quercus × filialis (Q. phellos × Q. velutina).

Photos taken on a few days from October 2012 through October 2013.

A large, cultivated tree at Duke University with somewhat narrow, small acorns (around 1.5 cm long).

The second-to-last photo is a modified screenshot from Google Street View (Sep. 2014 picture) showing the tree, and I added the red arrow. The last photo is a modified screenshot (again, I added the arrows) of this tree when young and recently-planted in the early 1930s. The original and enlargeable photo can be found here: https://www.flickr.com/photos/dukeyearlook/6900485120/in/album-72157621179687840/

Duke's historical photos can be found here: https://www.flickr.com/photos/dukeyearlook/albums

and here: https://library.duke.edu/rubenstein/uarchives/history

This tree was cut down in 2020, not sure why.

Wooo! he emerged!!!
For it being the largest mosquito species in the US, it does seem kind of small, although it's definitely very loud when it flies.
baby picture: https://www.inaturalist.org/observations/128965436
Found in a root phytotelma of a Fagus grandifolia, reared indoors.

I find the spectrogram very interesting. It looks like the fundamental frequency is at about 800Hz. Crickets and most other things I've recorded have very clean songs without harmonics, so I was surprised to see the lovely harmonic series on the spectrogram. I'm also surprised by how low the fundamental frequency is, I would have thought it was much higher. Mosquitoes sound very high-pitched!

Cercis canadensis
This gall/mine had no sign on the top of the leaf; On bottom, all galls had a characteristic black streak in the middle. Galls 4-5 mm.

I examined 122 leaf mines. 73% were empty, 21% contained larvae or pupae. Larvae are white, the pupae initially white before darkening.

  • 18 mines contained larvae (8 small, 6 medium, 4 large)
  • 7 mines contained pupae (6 white stage)
  • 2 mines had a midge pupal exuvium just outside the mine, suggesting that those individuals has wriggled out of the mine before emerging.
  • 89 mines were empty, either with an exuvium inside the mine (29) or not, or with signs of predation.

This species reappeared after a 53 year absence from the bay state, and in a brand new location.

A cultivated tree I've been watching for nearly ten years, and I suspected it was a hybrid because it's not like the other oaks planted here in a long row (all Quercus austrina), and is not like any oak species I know of. It has a dense crown with lots of fine branching; fairly small, semi-coriaceous leaves, with a few that persist well into the winter; and thick, pubescent twigs. I suspected that a live oak was one parent, but based on the leaf shape I wondered if the other parent was a post oak or a burr oak. I hadn't found any acorns until recently, when I found one very large acorn with a thick cap, which excludes any post oak species but is fitting for burr oak.

Another interesting thing about this tree is that twigs with fully developed terminal buds have powdery mildew on their leaves, whereas twigs without properly developed terminal buds have leaves free of powdery mildew.

-very strange oak
-few lobes, some even look maple-like (this is definitely way out of range for maple-leaf oak!)
-site is wet forest on black, organic soils over dense clay
-this tree is in a very diverse oak community that includes Q. shumardii, Q. palustris, and Q. rubra which it may be a hybrid of.
-acorns are very large, have faint striping
-leaves have orange tufts of hair at vein/mid rib junctions on leaf undersides (like Q. shumardii does)
-is it a Shumard oak with strange lobes?
-is is a Shumard hybrid such as Q. x riparia (Shumard x red oak hybrid) or Q. x mutabilis (Shumard x pin oak)?

My best guess: Q. x fernowii, a hybrid between post oak and white oak. The leaves have more lobes than typical on a post oak. I found other post oaks in the park with leaves that have the classic Maltese cross shape.

This is a problematic cicada! Though clearly cassinii (that's all that has emerged in my location), it has an aberrant orange patch behind its right eye. The patch extends onto the pleura, and (interestingly) there is an orange patch on the right side of the head as well, between the eye and the cibarium (photo 5). This casts a little doubt on septendecim IDs made exclusively based on the presence of thoracic patches, and reinforces the importance of side + underside shots for ID.

I'll be interested to see if I encounter any more like this one; it may be a rare aberration.
