    1. The problem statement, all variables and given/known data
    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.
    2. Relevant equations
    ---.

    3. The attempt at a solution
    I don't know where to start.
    i do know about bacteria that can grow on metal- Magnetotactic bacteria.
    But nothing about these kind.
    Thank you in advance.:smile:

    Insect eggs on stalks. Not uncommon.

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