Call it the cuckoo of butterflies. Like the well-known birds, the Alcon blue butterfly has found a way to get others to raise its offspring. Researchers in Denmark report that the large blue butterfly has managed to produce larvae with a chemical coating similar to that of the local Myrmica rubra ants.
