I took a few pictures of an insect last night, and I really have no idea what it is, and am very curious to find out. Would it be off topic to post it as a question to see if anyone else can possibly classify it?
Yes, it would be off topic, but you can always hop into Chat and ask there. The room is persistent so even if there's no one there they will see it when they join later.
There are, however, several "what's that bug" sites on the internet you could turn to.
On-topic would be: "How can I take a better picture of this bug, whatever it is?"
On-topic would also be: "I came across this daguerreotype of an insect. Is the photographer known, and what was the historical importance of this artist, image, and technique?"
