Idk, I feel like the colourful ones would group a bit differently.

The popular high-fashion ones (orchid mantis, jumping spider, rosy maple moth) would be at one table, goths (bumblebee, tarantula) at the other, jocks are already together (beetles, tho ladybug prob carries a knife), goodly two-shoes nerds (bees) also, other spiders are obv commuter nerds, …

Anyway, I would skip lunch bcs this feels like a way too social situation.
