Wonderful images as always. I have noticed a few posts in which samplers are finding fewer species. This in light of the recent UN report on forthcoming extinctions.
One of our state departments monitors the levels of microcrustaceans in streams and rivers as a sign of a healthy food chain. I myself have found that ponds previously dependable for an array of species have recently become mundane.
Has anybody else noticed this?

Regards
Mike

Hi the protist looks like it has a stalk and a bell though I have never seen one with that surface texture. I believe it belongs to the group of Peritrichs - Vorticella sp.

I checked my Illustrated Guide to Protozoa and didn't see anything that appears exactly the same. Closest species seemed to be Vorticella picta - but you may need a ciliate expert to identify.

Bruce Taylor is a cliiate expert who might be able to identify the species - you can visit his web site:
http://www.itcamefromthepond.com/ and contact him - he has helped me identify ciliates and he sometimes identifies ciliates for folks on this forum, he is very helpful.

Cheers
RB

Thanks Very Happy

Walter, it is beetle's larva.

Robert, I think it's also a Vorticella.

For the peritrich, that type of line pattern is typical of Pseudovorticella, in contrast to true Vorticella which only have horizontal lines. The two are very similar but it turns out became solitary independently. I understand it sometimes takes silver staining to distinguish them but not always; Bruce Taylor has noted that lines may be brought out by slight compression, and in species like P. monilata they are marked by little bumps. In your photo it looks like they are on top of a clear margin of cortical vesicles, which is characteristic of other species like P. chlamydophora.

The water flea, in case it also needs an ID, looks like Scapholeberis.
