Homework Statement

I'm not able to identify this, i found it on my window railings.
Could you help me out.

Also, they are attached firmly to the railings, i couldn't blow them away, i tried pulling out a few the white parts comes off easily, but the stalk(if i can call it so) is hard to pull out, by hard i mean, there is some, more than expected resistance, but doable. A bit slippery also.

But nothing about these kind.
Thank you in advance.

Insect eggs on stalks. Not uncommon.

Which insect?

You ARE aware of the fact it depends on where you live (and I guess you are not my neighbor)?

Ok, i thought its just specific to a particular insect.
