Did you find it in a rock pool at the sea?

yes, there was a small clump of algae on a rock while i as photographing a chiton, and one small part of the algae started waving around independantly of the water movement, that's when I noticed it was some sort of algae-like case

would have been at about the mid upper tide area, in a rockpool, about 100mm water coverage from memory

Great stuff, then it's definitely a marine caddisfly larva. The most common species is Philanisus plebeius but ideally an adult would be needed to confirm the species.

Thanks Brian. I'm assuming the adults would be found over the rockpools? What sort of conditions would likely be best to encounter them? I could try and get a photo of an adult

The adults can be seen hanging around the rocky shore during the day. They will look like small moths and most likely have a short erratic flight when disturbed.
There are some excellent photos on Naturewatch to compare anything you find

I hope this helps :)

@tangatawhenua this one has 5 obs over the last 5 years, but it's interesting all the same, as caddisflies are normally a freshwater thing. Do you want it added to the project?

I have added this to our project as it has 5 obs and as yo0u say interesting. I have not looked for anything else like this before so will help to open my eyes and horizons *LOL*

I think this project is a great idea, as there are often organisms we don't see because we don't know they are there. When we see other observers posting them, it's a great headsup of where and what to look for, and often they are a seasonal or "short window of opportunity" type thing.

That is exactly why I did this project - and give me other things to look out for to amuse myself :)
