A Fly Named Anthrax pluto

by Eric Neubauer

When I review my photos and decide what to upload to iNaturalist, the first thing I do is separate them into broad categories such as flies aka Diptera, and today was the day to work on that group. One was this shaggy, spotted fly found in a wooded area near Alligator Creek.

Sue Ann now declares this her SECOND favorite fly.

I don’t know my flies very well, and trying to identify one I’ve never seen before is like going down Alice’s rabbit hole.

There are so many different kinds of flies. A fair number don’t even have a single observation at iNaturalist, but I thought this one was distinctive enough and I might get lucky. Way down in the low double digit observation totals of Texas flies, I finally found one with similar spots. It was in the Anthrax genus which I’ve never encountered before.

The word “similar” is a dangerous one and it has burned me before, so the next logical step was to search the genus Anthrax in Texas. And what do you know, there was another nearly identical species down in the single digits! Now, how am I going to tell them apart?

The only consistent difference I could see was that the leading edge of the wing of one was solid black and alternated between black and clear on the other. Mine was the one with 7 observations, now increased to 8. The only other observations for this species in North America are four in eastern Canada, oddly enough.

Found Some Austin Natives

by Sue Ann Kendall

I love it when I go for a walk and see things that you’d only see right where I am. This afternoon in Austin, where my housemate and I were enjoying some sun after all that rain over the weekend, I found these guys. Here’s an excerpt from a longer post on my personal blog. Let me know if I’ve mis-identified anything!


Today turned out to be beautiful. Anita and I enjoyed looking at some of the native plants and insects we pass by on our walks. Two were right outside our house, next to a steep rocky slope.

Cedar sage outside the Bobcat Lair (our Austin house)

No matter how hard the landscapers try, they can’t get rid of all the beautiful plants that were here before the development was here. Case in point is the cedar sage you see here. Its native habitat is cedar brakes on caliche, where the ashe junipers are located. They like the rocky hillsides. Yep, that’s accurate! These beautiful flowers cover the rocks our house sits on, right under the native trees that got to stay when the neighborhood was built (now they qualify as “heritage” cedars, so allergic people can’t cut them down).

Slender false pennyroyal

Nearby were these lovely little plants with tiny pink blossoms. There are many tiny plants with pink blossoms this time of year, but these looked different from all the others I’ve been finding. Sure enough, they are slender hedeoma (Hedeoma acinoides). There is not much about them in iNaturalist, but a quick check of their habitat shows it’s mainly the middle of Texas. It’s a local! Further checks on the Wildflower Center site found that their common name is slender false pennyroyal. I learned something new!

At the mailbox, my housemate, Anita, started jumping around, and I saw that there was a large winged insect flying and landing, which caused that reaction. I got everything nice and calm so I could photograph it.

It appears to be a crane fly, but I’m not sure which one it is. It could be Tipula tricolor or Tipula furca, juding by the wings. I assume someone on iNaturalist will set me straight. I thought it was nice of the crane fly to hold still so I could get such a good picture!
