Moved from False Honey Ant.

I believe these are Prenolepis imparis. They must have been using the watering can to incubate their adult staged brood. Nuptial flights usually occur during the first warm day of the year after January in the late afternoon. Most often they occur in March but can occur as early as February and last as long as April-ish. Queens are a pretty orange-brown with red blushing.

The light brown males simply need to gain their full color. When they fly you can see swarms of them gathered around trees.
