Link to paper: Megaphragma is a tiny parasitoid wasp that shows complex behaviors despite its miniscule size.
Chua et al. map the compound eye and the lamina of micro-wasp Megaphragma viggianii in the same specimen with a few-nanometer resolution. The stereotyped cartridge connectome is similar to but simpler than that in larger insects. Dorsal rim specialization in photoreceptor morphology is reflected in the differences in downstream cartridge connectomes.
