Limnephiloid Snail Caddis
A tiny caddisfly that builds a perfectly spiraled case from fine sand grains cemented with silk. Larvae scrape algae from rock surfaces in clear streams.
Did You Know?
The coiled case provides structural strength far exceeding that of a simple tube of the same material.
Great Helen
A large, elegant swallowtail with dark velvety black wings bearing a broad white band across the hindwings and blue submarginal spots. The hindwings have distinctive spatulate tails.
Did You Know?
Males are often seen mud-puddling in large groups along forest streams, sometimes alongside dozens of other swallowtail species.
