I noticed this odd, fuzzy patch of tiny green spheres on my window this morning. ([Picture](http://picasaweb.google.com/lh/photo/nKaeWL6sU-GLCk9qvlyh3Q?feat=directlink)) The dimensions of that stripe are about 1 x 0.25 inches (25 x 6 mm) That’s a macro shot, but I didn’t put anything in there for scale. Anyone have a clue what it is? My first impression is an egg cluster from some sort of insect. But I’m no entomologist. ---

Those are insect eggs. I can’t tell you what kind. ---

Happy news, those are not cockroach eggs. Now you get to wait and see. 🙂 Send pictures of young’uns please. Tina, One of the bug lovers. ---

> [@Serenata67](#): > > I thought spider eggs were nearly microscopic. At least much smaller than that. They’re from a big spider. A **BIG** spider. Outside of **aerodave** ’s window. With just a flimsy screen between him and them. 😃 Actually, the spiders’ eggs I’ve seen have been in roughly spherical silk containers. The ones in the OP are probably not spiders. (Not that I actually know; just going off of what I’ve seen before.) ---

I’m wondering: Could they be moth or butterfly eggs? ---

**Johnny** , I think you might be on to something. A google image search of butterfly or moth eggs leads to results that look very similar: pale yellow or green arrays of tiny spheres closely packed. I’m fairly satisfied that’s what it is. ---

Pity. I was looking forward to a thread about giant mutant spiders tearing at your screen. 😃
