Green Lacewing - Ceraeochrysa smithi

Green Lacewing - Ceraeochrysa smithi
Houston, Harris County, Texas, USA
November 2, 2016
Not sure of the exact species of Lacewing this is, but that's not why I'm posting. I noticed it's odd behavior on a small twig late at night. It was secreting a white substance from its abdomen and was fixated on it. Now several years ago I had looked extensively online and discovered what this behavior was, but it has been so long I seem to have completely forgotten, and I haven't found out since. Can anyone please elaborate what exactly it is doing with this behavior? Any insights are appreciated.

might be laying eggs?
I think they lay them on the ends of thin filaments.

 
It could also be grooming, I'
It could also be grooming, I've seen similar behavior in mantises and katydids.

I can't say I'm terribly familiar with what I'm seeing here, but I'd wonder if it's related to something that's more familiar. So at least as far as oviposition, there's a fluid produced by the abdomen that solidifies into a strand of silk. They will also use saliva sometimes on the surface that they'll place a strand. This is also sometimes done to themselves as a sort of maintenance or grooming. In C. smithi, there's additional droplets of oil that are applied to the silky stalks that seem to act as a defense against predation. This oil, though, is also often apparently consumed by the larvae.
