Article Synopsis
- * A study examining 25 caddisfly species identified 123 opsin sequences, revealing that LW opsins show the greatest diversity, creating two distinct clades in the opsin gene tree.
- * The study found that half of the caddisfly species lost the SW opsin, likely due to their adaptation to low-light environments, while all species had a single UV opsin copy, except for one (Athripsodes cinereus) which
Insect silk is a versatile biomaterial. Lepidoptera and Trichoptera display some of the most diverse uses of silk, with varying strength, adhesive qualities, and elastic properties. Silk fibroin genes are long (>20 Kbp), with many repetitive motifs that make them challenging to sequence.

In the Chikuma River population of this alien amphipod, egg-bearing individuals were found throughout the year. In terms of egg maturation cycle, egg development (during embryogenesis), and egg count per ovipositional cycle, these amphipods display a very efficient reproductive system.
