Harvester Ants with a Spider?

Category: Insects | Date: Aug 26 2007 | By: tumaren

Hi, this is Kerry. We were packing up camp on the Ewaso Nyiro River and noticed Harvester Ants carrying a Spider to their hole. They slowly took off it’s legs and took them down the hold and then finally tried to get the body of the Spider in to the hole. I have only ever seen these ants harvesting vegetable matter and did not know they would have any interest in a Spider?

I have also seen these large harvester ants (Messor cephalotes) capture insects in Kenya.

Thanks Jeean-michel,
since posting this i have met several others who have seen this species consuming insects. interesting. are you aware if this species harvests the seeds itself normally or a fungus that grows on the seeds (like leaf-cutter ants in south america) ?

They only eat the seeds as all species of the genus Messor.

Well, here in Lassen County (California, northeastern high desert , upper Great Basin)these things are a big pest. We call them fire ants, though they don’t have tall mounds like their cousin, they burn like fire when they bite you, and they are aggressive. They are harder than heck to get rid of. Boilig water is the only solution, but you need 20 gallons of it because their nestsw are quite expansive underground. We don’t like to use poisons on anything as we have chickens and cats and other loose animals. But I have resorted to gasoline, lit gasoline, bleach, toilet acid, rubbing alcohol, digging them up, standing over them with a torch, etc. They march off with my chicken feed and seeds when I am trying to establish a stand of pasture. They are meat eaters. Or I guess omnivores. Opportunists would be a good description. And I have found more than one queen in the hill. That’s the hardest part about getting rid of them. I have dug up the nest to torch them and I’l see many queens coming out, so they just start over if I miss one.

Delia,
These Harvester ants are not nearly as damaging as Fire Ants. They are also native to here (unlike fire ants which are exotics in the states). Where my mum lives in Florida, Fire ants are an enormous problem, not only painful but a pest for agriculture and a major environmental issue - they kill just about every native ant and other invertebrates. I hadn’t realized that fire ants had reached as far as north eastern California. I do know that there is a particular insecticide that they use on fire ants that is not dangerous for other animals. you would have to look around on the internet to get its proper name. Its sold all over the south eastern states. cheers, james

Many harvester ants are native to the US and most are non aggressive. There is really no reason to exterminate them, as they do not enter human dwellings. Messor harvesters can’t sting the way their Pogonomyrmex cousins can.
