Limnephilidae

Several possible species in the Limnephilus genus. Are these just empty cases or are they occupied?

Hi Inopinatus, These were

Hi Inopinatus,

These were occupied cases, I could see the larvae poking their heads out of them.

There is a group of species

There is a group of species that make cases like this Limnephilus flavicornis, marmoratus, stigma, politus and rhombicus but not lunatus as suggested as the pieces are laid across the axis of the case not lengthways as in lunatus. Identification to species needs a good microscope and a key but they can be admired without going that far. Some individuals get very fixated on one sort of particle and even use snail shells or even living snails.

Ian, Thanks for this info.

Ian,

Thanks for this info. There is a very interesting variety of caddis at this particular water throughout the year. I am only really scratching the surface so far in IDing them as adults never mind the larvae.

In time I hope to get a better idea of which species are present and hopefully iSpot will help me establish what they are.

Thanks again.

Cathal.
