I hope to never meet someone who doesn't know how to use a search box.

Lol. Yes its anime. I stated it  on the 2nd line. Like the other guy said use the "search box".  There are two seasons and at least 4 ovas (if I remember correctly the ovas are only subbed). There are subbed and dubbed versions for the 2 seasons but you will probably have to request them on Nyaa. It hasn't been uploaded here in a few years. Sometimes you get lucky requesting here but more often than not requests for dead threads are never seen. It has mixed opinions on the reviews but I enjoyed it. My biggest problem with it was one of those series that should've been at least 25 episodes per season and they compacted them into 13 so a lot of stuff was rushed and skipped. that pissed a lot of people off. Still it was interesting to see how the ants got smarter and smarter. If you can get over how the series is rushed its enjoyable. If you cant then you may not like it.

But yes its very very very dark. A lesson on how using science in the wrong way will end humanity.
