As part of the Global Butterfly Week, I will be talking about "Why and how butterflies display different color patterns on different wings, surfaces, and sexes" over zoom tomorrow. If anyone is interested, link is below.

Here is a very detailed examination on how pigmentation in the cuticle of a butterfly wing scale changes the density and refractive index of chitin and, thus, also alters structural color. https://t.co/6ZUi87y0PG
For those interested in the evolution of phenotypic plasticity - Shen Tian et al. found that a novel bit of DNA - a Hox gene promoter in the genome of satyrid butterflies - boosts plasticity in the size of their eyespots in response to temperature.

Butterfly larvae can pass on a learned odor preference to other larvae via a simple hemolymph transfusion. Short film about the work (published today) by my daughter Florence:

@seth_donoughe Hi Seth, here we just show a parental effect (maternal, paternal, or both) but previous experiments showed a paternal effect (see Gowri et al. 2019) on odor preference inheritance.
I am looking for an enthusiastic student who wants to perform research on sound communication in butterflies, or on odor learning in butterfly larvae, at the organismal and/or molecular levels (e.g., brain circuitry and single-cell gene expression levels). Fellowship available!
