Fire ants (these appear to be native Southern fire ants, Solenopsis xyloni, but could be imported Solenopsis invicta) make trails from their principal burrows to a good food source requiring extended dismemberment and caravan work. This trail is 48 feet long. In north Georgia, we would only see parts of these trails, as most of them would be beneath a thin clay roof. The sand here will not support such structures. All of the mounds I have seen have been in grassed areas, where I presume that the grass roots help support the burrow.
Spiders are everywhere. I hope they are eating mosquitoes. Many small ones drift down into the boat on their wind-blown streamer webs. Some work around the outside and occasionally the inside of the tent. I’m happy to have them.
