Where & When
Time Of Year (?): Fall
Neophylax caddisflies emerge in concentrated numbers in the fall because they enter diapause (Diapause: A state of complete dormancy deeper even than hibernation. While in diapause, an organism does not move around, eat, or even grow. Some caddisfly larvae enter diapause for a few weeks to several months. Some species of microscopic zooplankton can enter diapause for several hundred years.) during the summer, which synchronizes their emergence to within three weeks on a given stretch of stream.Hatching Behavior
They emerge in the surface film.Egg-Laying Behavior
The ovipositing behavior of this genus is not well-documented, but what is known varies by species.4 Caddisfly Specimens in the Genus Neophylax:

A variety of cased caddisfly larvae, probably mostly Neophylax, have clustered along the backside of a rock in fast water. There seem to be some Helicopsychidae larvae clustered along the bottom, and a few other taxa are mixed in. It's interesting that several larvae have especially large stones placed over the front openings of their cases, perhaps to block the case off for pupation.
It does seem to be the wrong time of year for Neophylax to be pupating, but that was the ID given for one of these which I collected and photographed up close.
