Hello Ran; I’m not aware of any ant that migrates. The definition of migration is very imprecise and varies from one source. Here is one https://en.wikipedia.org/wiki/Insect_migration The key idea here is that the movement is seasonal and bidirectional.

For example, the army ants don’t make a permanent nest but wander for a time, stop for some days to grow out a batch of larvae and then wander some more. This goes on for the life of the colony. I wouldn’t consider that to be migration.

Many other ants, when the nest is disturbed, up stakes and colony absconds and sets up a new nest some distance from the old one. But this isn’t seasonal nor bidirectional. I've never read a Lasius paper that suggested migration.

I would be interested in what your other correspondents have to say. Best regards, Jim Des Lauriers

James Des Lauriers s Des Lauriers thank you very much and apologies for my late response. For clarification. Yes by migration I mean moving from one place to another, or moving the ant nest after a disturbance occurred, as in this example: https://link.springer.com/content/pdf/10.1007/s00114-016-1386-8.pdf?error=cookies_not_supported&code=b20c8921-6d55-4aca-9013-2367154ede68.

Are there any published classification on the different patterns of ant movement, such as in daily foraging or nest-moving?

Hi Ran; You can get an introduction to the topic in -
