Nature’s little builders 🌿 In August, some of our monitors found as many as 1000 cased caddis in their sample!
Caddis larvae make protective cases from twigs, sand, and stones. Each one is unique!

Figure 1 in van Leeuwen et al. (2025): "Map of the world with bar charts per continent that indicate the total number of families in each insect order. The colouring of the bars indicates the number of families in each order, with unavailable (orange) and available (blue) length–dry mass power regression parameter information (see Figure S1 for a similar figure at the genus level). The Megaloptera category includes the Neuroptera families."

A cheliped, the large pincer of a crayfish, left on a lakeshore. There is first, the big two-pronged claw, behind it, a sort of elbow, and a second section, this one with pinkish teeth along one edge. The cheliped is sun-bleached to a mostly whitish tone, with pink spots and bluish tints. It lies on wet stones in the rain, with a few dead leaves, a larger, brown stone, and a bit of half-dead grass.
