Most of us don’t think about ants very often unless they’re marching across our kitchen counter (or up our leg). That anonymity isn’t their fault, it’s ours. Ants play major roles in ecoystems, and their biomass in prairies can rival that of bison, so if we’re not paying them sufficient attention, that’s on us.
I took the two ant photos in this post at the Niobrara Valley Preserve back in June of this year. As is usually the case, I spotted the ants only because they happened to be crawling around on some flowers I was looking at. Ants are often spotted on flowers, especially those that have easily accessible nectar that helps satisfies ants’ attraction to sweets. While they don’t usually do much good as pollinators, ants might provide some protective services for plants by helping to keep herbivores away.
Ants spend most of their time underground, of course, where it’s easy for us to forget about them. When they’re not in their tunnels, they still aren’t all that visible unless we’re looking for them. Regardless, they are major predators in prairies, collaborating with each other to take down prey much larger than they are. In addition, ants are scavengers, major forces in nutrient cycling, and important seed dispersal agents for some plant species. Ants can also steal food and workers from each others’ colonies, “herd” aphids and harvest their honeydew and meat, and are themselves an important food source for other animals. We should probably stop ignoring them.
Most prairies probably have around 30 species of ants living in them, which is more local diversity than is found in grassland nesting birds, which we pay infinitely more attention to. In addition, if we lost all our grassland birds tomorrow, it would be sad, but I’m pretty sure it would have much less impact on prairie ecosystems than if we lost our ants.
Let’s try to keep them both around, shall we?
