      This is called Müllerian mimicry. Toxic / poisonous / venomous / dangerous animals tend to look like each other. This enforces pattern recognition. You can see this within wasps / bees. The textbook example is the Heliconius butterflies. PC: Meyer A, PLoS Biologypic.twitter.com/lhhlqQdJ6x

      The other side of this is Batesian Mimicry. A non harmful thing mimics a harmful thing. Basically banking on that predators have learned established patterns. Here are a bunch of hover flies. (Syrphidae) They're all are generalized bee mimics. PC Alvesgaspar CC by SA 3.0pic.twitter.com/lCs1aAdsde

      In old textbooks you'll find that we thought the Viceroy butterfly (top) was a batesian mimic (not harmful) of the monarch. However a study in the 90's showed that both the viceroy and the monarch are toxic making them mullierian mimics Pc DRosenbach CC by SA 3.0pic.twitter.com/U4Qvua9hV0

      Some of the most common batesian mimics are flies mimicking bees. Here's a convincing syrphid fly. PC: Copyright © 2015 Joy Markgrafpic.twitter.com/JW3uKnWQcv

      But lots of things have mimics. Tarantula Hawks have one of the worst stings in the insect world. But it has a little katydid mimic (left) that is harmless. PC: @FieldMuseumpic.twitter.com/vMRDsjwr2U

      We think that butterflies have eye spots because they mimic vertebrate eyes that might otherwise be a predator to their predator. Owl Butterflies (Caligo sp.)pic.twitter.com/Um44jKUCDV

      How do you get butterflies to hang off your fingers like that? Or are these dead ones?

      They're in a butterfly garden. Born and raised so they're pretty lazy and are super chill with people.

      I had no idea they had enough of a brain for that kind of conditioning to occur 🤔

      Yup! Bugs are totally trainable. Maybe I should do a thread on this ...

      Yes please. I thought you needed rat-sized mammalian brain at the minimum to do any sort of behavioral conditioning
