I’m continually impressed by the collective knowledge of the readers of this blog–identifying mystery plants, recognizing the face of a walkingstick nymph, and so on. So I’ve decided to start a monthly feature wherein I post a nagging natural history mystery and see if anyone knows anything about it. Some of these I’ll have more to say about than others; this month’s will be a quick one because I have ten reports to write by the end of the month.
When Noah and I were traveling four years ago in search of things to photograph for our book, we stopped at Yosemite National Park briefly to find Sierra wormlions. While we were in the valley, in one area we found a bunch of these 3-mm banana-shaped things stuck to pine needles. In photos, they look like they could be larvae, but they were hard and stationary and in person they gave the impression of eggs. There were often several in an evenly-spaced row, and all had tips that curved away from the substrate as shown below.
So, any thoughts on these?
We found them on July 26, in case anyone feels motivated to try and find more of them.
