The paper identifies apoptosis as a conserved mechanism maintaining worker sterility in Polistes wasps by comparing ovarian structure and cell death rates with Drosophila.

The paper examines how sex, body size, and mate location behavior influence eye structure and visual acuity in Centris pallida bees, finding sex and morphological differences in eye characteristics.

The paper examines neural investment in defense-specialized soldiers of the stingless bee Tetragonisca angustula, finding that relative visual brain investment varies with task demands but not with repertoire size.
