Post update: Tachopteryx thoreyi exuvia

I just updated an older blog post in order to correct a label for an anatomical structure that was mislabeled, plus I added some new information.

The updated annotated image is shown below.

No. 2 | Gray Petaltail (Tachopteryx thoreyi) | exuvia (dorsal)

While I was editing the photo, I noticed something I hadn’t seen before — a large dorsal hook of abdominal segment nine (S9) that overhangs segment 10 (S10). This time I’m fairly sure the structure is correctly called a dorsal hook.

One of my projects this season is to locate and successfully photograph exuvia. Off to a poor start so far! I’ve found a couple of great-looking spots and hopefully they’ll produce as the season progresses.
Thank you for the motivation!

  Pick the low hanging fruit first. Look around the edges of ponds and lakes where there are lots of skimmer dragonflies — their exuviae are relatively easy to find but DIFFICULT to identify to the species level.
