Entomology (Study of Bugs)/insect?


If you can visualize what Iam saying it would be helpful, so I will do my best. I noticed this brown grassy stuff sticking out of the tracking where my screen slides up and down. I lifted the screen to get the grassy substance out and low and behold out drops a bunch of those brown egg like pods or something about the size of a good size rice. I assume some type of insect is doing this. I did spray some insect spray but wonder what it can be. Hopefully this pic will show a good example of one of these


Well, I am not sure what the object is in your picture, but I can tell you what is packing your window tracks with grass....

That would be a grass-carrier wasp in the genus Isodontia .  Grass-carriers are solitary, only one female per nest.  Here's a couple of blog posts I did on this since I am often asked about the window tracks phenomenon:

I hope you will reconsider "spraying first and asking questions later."  Very few insects are genuine pests, and we need to learn how to live with the occasional nuisance.  Thanks.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
