I don't think that's correct- the nature article about the article says they don't, https://www.nature.com/articles/d41586-024-03190-y and drosophila are not eutelic (although I see that some insects do have "partial constancy"). Could you ask the author to clarify?
Looking in the paper more closely they say:
"""After matching, Schlegel et al.12 also compared our wiring diagram with the hemibrain where they overlap and showed that cell-type counts and strong connections were largely in agreement. This means that the combined effects of natural variability across individuals and ‘noise’ due to imperfect reconstruction tend to be modest, so our wiring diagram of a single brain should be useful for studying any wild-type Drosophila melanogaster individual. However, there are known differences between the brains of male and female flies46. In addition, principal neurons of the mushroom body, a brain structure required for olfactory learning and memory, show high variability12. Some mushroom body connectivity patterns have even been found to be near random47, although deviations from randomness have since been identified48. In short, Drosophila wiring diagrams are useful because of their stereotypy, yet also open the door to studies of connectome variation."""
i woudl expect the overall architecture to be the same, but not the cell identities or the connections. But as always, I'm happy to be shown wrong with facts.
