About

Of the 200 species of caddisfly in the UK, the Land caddis, or 'Terrestrial caddis', is the only one that lives on land throughout its whole lifecycle; the others all live in water during their larval stages. The Land caddis is most abundant in woodland leaf litter from December to March when it is in its larval stage. As with other caddisflies, Land caddis larvae construct a case made of sandy grains in which they develop. The adults emerge in late summer and early autumn to mate, and the eggs hatch a month or so later.

What to look for

The Land caddis is most identifiable as a larva encased in sandy grains. The adult females are flightless and much smaller than the males.

Where to find

Restricted to Worcestershire and neighbouring counties.

Did you know?

Land caddis females are thought to excrete pheromones to attract males. They emerge and mate in late summer and early autumn, living for just a couple of weeks.
