I was thinking about similar annotations with moths actually. I’ve annotated the sex on a few moths where the female is flightless so it’s clearly the male in the light trap.
I was recently working on a personal project with a certain species of plant that only had about 30 observations and I filled in all the annotations for those which was quite helpful in establishing flowering periods in the wild vs in cultivation. I was wondering if someone was researching distribution of a species based on gender, or something similar, whether a ‘pair’ observation would just cause them problems.
