And of course lifestyle, or rather, ecological niche specialisation, tilts the vision-olfaction trade off, here in wasps:

“Differential investment in visual and olfactory brain regions is linked to the sensory needs of a wasp social parasite and its host”, by Rozanski et al. 2021 https://onlinelibrary.wiley.com/doi/full/10.1002/cne.25242

This work compared the eusocial wasp Polistes dominula with its obligate social parasite Polistes sulcifer.

The tradeoff between vision and olfaction has been studied in flies. There’s a strain of Drosophila melanogaster that’s been reared in the dark for decades: the so-called “dark flies”. Here, the authors examine the effect of rearing “dark flies” in the light for 1 and for 65 generations, and observe how brain regions for vision are boosted even within 1 generation:

"Phylogenetic tracing of midbrain-specific regulatory sequences suggests single origin of eubilaterian brains", by Schuster and Hirth, 2023 https://www.science.org/doi/10.1126/sciadv.ade8259

A genetic signature of bilateral animals with brains, including "a genetic boundary separating the rostral from caudal nervous systems, demonstrated for the metameric brains of annelids, arthropods, and chordates and the asegmental cycloneuralian and urochordate brain"

In other words, the genetic toolkit of the ancestor of both protostomes (arthropods, nematodes, molluscs and annelids) and deuterostomes (echinoderms and vertebrates) – the eubilaterian.
