How long do they live? Bare with me a minute here and hopefully you’ll understand why ants made this list. Worker ants live approximately 1-2 years and male ants live only a week or two, but queens can reach or even exceed 28 years . Another odd finding is that the expression of superoxide dismutase 1 is decreased in queen and worker ants compared to males. This is strange because overexpression of the enzyme superoxide dismutase 1 (SOD1) actually increases the lifespan of fruit flies 
Where are they found? That would be pretty much everywhere. Here’s a picture. They’re found in the black regions, which I can only assume is because the ants are black, but honestly the picture looks a bit ominous.
What do they eat? Everything, they’re ants! They prefer ripe fruit, insects, your sandwich, and breaking into your home through unknown spaces to steal whatever crumbs you left in your sink (I’m not bitter).
What do they look like? Well, like this:
When males and the female queen mates, they are winged. Once the female mates with the males she will lose her wings, then dig a tunnel to lay some eggs in and live a really long time. The males, on the other hand, mate and die within a few days.
How do they reproduce? This is where things get weird. The queen has sex with multiple males during that winged mating ritual, but that’s it, she never mates again. She stores sperm inside of her and fertilizes her eggs depending on what sex she wants her offspring to be. Fertilized eggs produce worker female ants, whereas the unfertilized eggs develop into males . In all honesty, ant reproduction is fascinating, but not the point of this website, so I will move on now. By the way, those males that die quickly also have shorter telomeres than the queens and the workers .
How do scientists know how old they are? Well, luckily there are scientists that have kept ants in captivity and measured their lifespans firsthand .
So what are we lacking? There are still a lot of questions about the differences in SOD1 expression and telomere length in these ants. There’s information regarding the nuclear genome of Lasius niger on NCBI (National Center for Biotechnology Information) .
Please contact me if you have information that will add to the understanding of ant longevity.
