Squiggly 2  
The past week I keep finding tons of these squiggly line things on top of water in my pool and out of pool. These small gnat type flies I  think I identified the gnats as fungus gnats are swarming these squiggly lines. so i think it might have something to do with each other. I live in Hope Mills, North Carolina. Any help in identifying these would be greatly appreciated. I also already spoke to pool services about it, they said didnt look like algae. Thanks again. I attached a picture.

Answer
Dear Kristina - I will admit straight off that I have never seen anything exactly like these structures, but they most definitely are not fungus gnat eggs - see http://tinyurl.com/ljhto7r
for an image. The only egg deposits that I have seen with a similar shape are snail eggs, and those usually are on a solid substrate and are much larger than these. Rather, I suspect that they could be a colonial microbe/algae of some sort, You might try contacting your county office of North Carolina's Cooperative Extension Service to see if anyone there can offer an opinion - see http://tinyurl.com/n6jlb7p for contact information.

Sorry not to be of more definitive assistance,

Expertise

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
