"The 3D ultrastructure of the chordotonal organs in the antenna of a microwasp remains complex although simplified", Diakova et al. (Polilov lab) 2022 https://www.nature.com/articles/s41598-022-24390-4
In other words, the insect's hearing organ (Johnston's organ) but not of the usual #Drosophila, rather, that of the miniature wasp Megaphragma viggianii.

For neuroscientists attending #sfn22: don’t miss the poster by Mitya Chklovskii’s group describing the completion status of the whole brain #connectome of the fairy wasp #Megaphragma, of expected completion early in 2022. Find the poster tomorrow Monday morning, number 328.16 / YY35.
Mitya kindly shared the poster image publicly elsewhere.
This tiny #wasp is famous for being the size of a large paramecium (a unicellular organism) and for enucleating the vast majority of its central neurons while pupating. The adult has less that 10,000 neurons in its central brain yet it isn’t missing any organ or body part. See the paper that jumpstarted this effort:
