2. A larger version, with flash. 20x.

3. I believe this is an adult female, in one of the early adult instars. Correct me if I am wrong. She has no eggsacs. 10x.

4. Same bug using a 20x objective. It took 3 frames to get it all, then merged in CS4.

Mitch,

I like the second one.

Did you try polarized light with the last one?

Thanks Rogelio. I did not even think of using Polarized light. I was set up for flash, and it didn't even cross my mind. I guess I will have to try some tests tomorrow. :)

I was very glad to finally see an adult, although I think this one was very recently deceased. I saw no hearbeat, and in the same drop of water, were two of the naupliar stage cyclopoida.

Hello Mitch

I think that the first two pictures are the Naupilid stage of the Cyclops featured in your next photos

Thanks for looking JC. I did some research last night and found an image of the different stages of this bug. The first two aboce seem to more closely resembe the Nauplier stage N-2, while the last two look closest to the Copepodite stage, C-1.

I love how this knowledge thing works. I already feel much more comfortable with these guys, just knowing what I am looking at. And for sure, my aquarium has an abundance of these in the water. I am finding one or two of the Nauplier stage with ever pipette full of water. Which I assume, means I will be finding the Copepodite stages too. I did find one of the adult shed skins on the same slide, so I know they are in there. :)
