Your numbers imply silkworms have 2.50 (= 1.0*10^-5/ā(4*10^-6)) times as many neurons as black soldier flies. I expected adults to have more neurons than larvae, and ChatGPT guessed black soldier flies have 10 times as many neurons as silkworms.
@Laura Duffy, you assume the number of neurons of silkworms is 10^-5 that of humans citingChiba et al. (2010), but these may have meant to imply a ratio of 10^-6 (= 10^(5 ā 11)) for silkmoths. They say the ānumber of neurons of silkmoth brain is very few (about 10^5) compared with human brain (about 10^10)ā, which implies the number of neurons of silkmoths is 10^-5 that of humans. However, humans have 86 billion neurons, which is around 10^11.
