North Dorset Nature – Cadis Flies in Motcombe

Natalie Bourchier and Ben Hussey are ‘Down by the Brook’ at Bittles Brook Farm in Motcombe.

Today, they discuss an elaborate camouflage tube that cadis fly larvae build to protect themselves from predators. The pair found these insects in their pond recently.

Natalie explains why cadis flies are ‘exciting for medical researchers’, and why local artists and Jurassic Coast fossil hunters may be interested in these insects, too.
