TL;DR: It is inferred that closely related Heliconius species exchange protective colour-pattern genes promiscuously, implying that hybridization has an important role in adaptive radiation.

TL;DR: It is shown that a single gene, doublesex, controls supergene mimicry in Papilio polytes, in contrast to the long-held view that supergenes are likely to be controlled by a tightly linked cluster of loci.

TL;DR: It is shown that white versus yellow color variation in Heliconius cydno is due to alternate haplotypes at a putative cis-regulatory element (CRE) downstream of a tandem duplication of the homeodomain transcription factor aristaless, suggesting a role in repressing pigmentation.

TL;DR: It is shown that captive breeding, both commercially and by summertime hobbyists, causes migratory behavior to be lost, and the results provide a window into the complexity and remarkable fragility of migration.

TL;DR: Through a series of behavioural assays with the female-limited Batesian mimetic butterfly Papilio polytes, it is shown that males prefer stationary mimetic females over stationary non-mimetic females, but weigh female activity levels more heavily than female wing pattern when choosing between active mimetic and active non-reactive females.
