Too small for Dytiscus

Definitely in the subfamily Dysticinae though-the males have suction cups like in this individual...a few possible candidates (I'm guessing Graphoderus or Hydaticus)- please post additional images of entire dorsal, lateral, and ventral views of the insect; thanks!

Dytiscidae

I tried to post the three shots you asked for earlier today,
but kept getting the red flag, image too large to **load. I have
reduced them as much as I know how with my computer, have had the
problem many times before. Suggestions would be most welcome. Tks

MS Office Picture Manager

I'm not a graphics expert, but many software packages used to view images have options to reduce their pixel count.

If you have MS Office, look for the Picture Manager under MS Office tools. It's an easy one that I use sometimes. Then click File, Export, and choose the size (pixel count) you want from the pre-selected sizes.

Regardless, you need an software application that changes the number of pixels in the image, not just "resizes" the image, which may or may not actually change the pixel count.

For better advise, post your question in the BugGuide Forums section, under photography :)
