We have a question for the Consult-Ant today:


I have an ant question!

Over the years I have seen an unusual type of ant mound. It is a long, linear "mound"; actually a series of small mounds connected by tunnels of soil particles. The unusual thing about them is that extend in a straight line for several feet. Somewhere I heard these called "railroad ants", but I don't know if that is more than just a local name or description of the straight-as-a-string nest mound. I'd appreciate any information you might have about them, like scientific name or a reference where I could learn more. Thanks.



Since you don't tell me where you are from, I'm going to take a wild guess and suggest you might possibly be talking about a type of fire ant. Fire ants tend to build loose mounds that are sometimes long and narrow. (Except if they were fire ants, you'd probably know about them already).

Does the mound you are seeing look like the second photograph in this post?

If not, please let me know where you are located, which will help me narrow the choices. Also, roughly how big are the structures?

Anyone out there heard this common name and know more about it? Please let us know if you have some ideas.

(Note: As I mentioned previously, I have been the “Consult-Ant” on the Leaping from the Box website. I answer questions about ants and ant farms. From now on I will post the answers here, and when Karen has time she will also post the answers on her site.)
