But my favourites are the ones that look like poop. Birds stay away from their own poop because it carries diseases. So if you're a bug the birds prolly won't get near you.https://youtu.be/Q6ykX5hFxwE

But the best example is this moth. It looks like what is bird poop at the bottom of the wings and what look like two house flies pointing down lapping it up. PC

Alright. So let's up the game. So here's some background. You know when you see a potentially stinging thing. There's usually things you look for. Like orange. Or stripes.

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:

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?

Replying to @vgr
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
