Sticky, stretchy, waterproof, the stuff that holds it all together.

cased caddis housings are simply fascinating. used for protecting their fragile abdomens, to conceal themselves among all the stream bed debris and as ballast, these seemingly simple-minded creatures are pretty ingenious to say the least. the documentary footage is excellent, explanations simple. interesting for fishers and nature lovers of all ages, be sure to share this with your little ones, specially if they’re into creepy-crawly bugs, enjoy !
