AI Thread Summary
Leafcutter ants, specifically Atta cephalotes, can vibrate their mandibles at astonishing rates, reportedly up to 1000 times per second, although this detail is not confirmed by Wikipedia. The discussion highlights a desire for slow-motion videos to observe these vibrations, but no such footage has been found. The mechanism behind these rapid vibrations involves the ants stridulating while cutting leaf fragments, utilizing a cuticular file on their gaster that rubs against a scraper on the postpetiole. An article from JSTOR is referenced as a potential resource for further understanding this phenomenon.

Within a very quick google research, one reads that the jaws (mandibules I should say?) of leafcutter ants can vibrate up to 1000 times per second. Wikipedia doesn't say so though.
Anyway I wanted to see a slow motion video about the vibrations but didn't find anything. If you found one, please share it. :smile: I wonder what is the mechanism that can create such fast vibrations. If you know about this, feel free to share.

I am not an ant specialist, but I did some searching on the internet and found this article that might have what your looking for.


Atta Cephalotes stridulate during the cutting of leaf fragments by raising and lowering their gasters, so that a cuticular file located on the first gastric tergite is rubbed against a scraper situated in the postpetiole.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
