New ISpotter needs help?

This looks like a new post-er as far as I can make out. Might not be identifiable, but maybe someone can get a bit closer?

It’s been posted in the observations: I wasn’t able to identify it (“favouriting” it for another look): DJM has added a comment.

Angela’s first observation and she needs help.

Ben23’s first observation is about to fall off the carousel. He has suggested an identification and his photos are good.

Interesting to see that a new user has included a working EOL link. His first observation. Is anybody able to agree his ID or offer an alternative?

This new user is looking for help with a Diatom observation.

A new iSpotter has added lots of photo less observations making the carousel into a row of blanks. I’ve quickly posted 3 obs with pics to make the carousel look more interesting. Anyone able to add any more?
Like Mark Wilson, I’ve left a message for the new user re adding pics.
