These structures deter the butterflies from laying their eggs there, and more than that, these structures are actually nectaries that provide food for ants and other predatory insects that eat Heliconius eggs and larvae. So the yellow structure defense is two-fold: It deters the butterflies from laying eggs, and it attracts predators of Heliconius larvae. These back-and-forth counter-adaptations are what cause coevolution between predators and prey.
A predator is an animal that hunts and kills other animals for food. While some animals rely on camouflage, others, especially those with chemical deterrents, have bright or distinctive markings that serve as a warning to would-be predators called warning coloration. Some harmless animals take advantage of warning coloration and mimic other brightly colored species. There are also cases where two or more dangerous or unpalatable species all resemble one another. The end result of all of these interactions is that predators and prey evolve in response to interactions with each other.
These tight evolutionary relationships can result in coevolution , when two species evolve in a coordinated fashion by adapting to changes in each other.

These can both mean life or death for an insect so they are very important concepts to understand. Just like our crooks wanted to blend in with the dark night, insects often want to blend in with their surrounding environment.
They do this to avoid predation. The logic here is: Camouflage may be as simple as dark coloring but it can also be very elaborate. Some insects have stripes, spots, or other patterns that make them look like leaves, rocks, tree bark, and all sorts of other things.
For example, have you seen a stick bug? It literally looks like a stick so that it can blend in. The dead leaf mantis looks like, well, dead leaves, and the peppered moth looks like tree bark. Here, instead of trying to blend in to the surrounding environment the insect is mimicking or trying to look like something else. Just like our criminals pretended to be other people at the party, insects pretend to be other animals to ward off potential predators. Batesian mimicry involves a non-harmful insect mimicking a harmful insect.
For example, when a non-bee insect like the robber fly looks like an actual bee. So predators know to stay away from them. A good option might be to look like a stinging insect so that predators leave you alone, too. The idea here is that if a predator learns not to eat one dangerous insect it will learn to not eat all dangerous insects that look like it. A good example of this is seen with the monarch and viceroy butterflies. Both are unpalatable, and both look like the other. If you are a bird and you eat either one of these you will avoid both in the future.
So while both types of butterflies may have to sacrifice a few for the cause, they both also get a boost in protection. Get access risk-free for 30 days, just create an account. Finally we have self mimicry. This is when insects have a body part that mimics a different body part. For example, a moth may have a big spot on each wing that looks like two giant eyes. There are two benefits to this tactic. First, when these false body parts are flashed it may startle the predator and give the insect a head start on its escape.
There are lots of ways to hide out in the world and as an insect that someone wants to make a meal out of you, you will probably want to employ at least one. Two well-tested choices are camouflage and mimicry. Camouflage involves blending in with your environment to remain covert and hidden.
Camouflage can be as simple as coloration that matches the environment, or it may be as elaborate as patterns and body parts that look like leaves, rocks, and trees.
Some animals look like green leaves, others like dead ones, and others still like sticks and bark. There are three main kinds of mimicry in insects. Batesian mimicry is when a non-harmful insect looks like a harmful one.
Predators are less likely to eat something that looks like something is harmful, even if it is perfectly safe. Here, both are protected by each other because a predator is likely to avoid both even if it only knows that one is for sure harmful. This can startle the predator when flashed, but may also divert the predator away from attacking the really important body parts of the insect.
