Yes everything Ilona said, plus an ID. One more thing, it's generally best not to put a pin through small insects. With worker ants (not the case here) especially, distortions of the thoracic profile can impede identification. Ant people almost always mount specimens on points, e.g. see L. latipes specimens at antweb.org.

These ants start with wings, then break them off after mating in the air. Here's a picture of some winged ones emerging from the nest with their very yellow, but otherwise rather normal-looking worker ants:

Moved from ID Request.

Looks more like an ant to me. Not an ID but it looks similar to . It's preferable to trim your photos so we just see the insect and not so much white space.
