I do find it interesting the relationship between aquatic insects and wild flowers. How certain bugs and certain flowers appear at the same time year in and year out. The Black Caddis and the Trillium share this relationship. Trillium grandiflorum is often the first wildflower noticed by casual walkers; other spring wildflowers are much less apparent. ie the Trout Lilly (a very small yellow wildflower that is one of the first to bloom). Black caddis on the other hand are a smaller aquatic insect, and get far less coverage than the bigger Hendrickson. Black caddis usually range from size 16 to 18. With the females being the larger and also carrying around a little green egg sack.

Up to yesterday not having seen either a Trillium in bloom or a Black Caddis in the air. As I rounded the second or third bend in our float I noticed on the bank a blooming Trillium. Just as the first robin of the year brings memories of spring to mind, so do these three-petaled flowers. No more than a couple hours later I saw the tantalizing dance that all caddis share, as three or four caddis did there thing just above the riffling water. Now how does mother nature do that? The trillium and the black caddis are both known to share this time of year, but how do they plan their arrival for the very same day.
Thank you Ann Miller for sharing one of your amazing images, thank you for the use of your black caddis.
