The other side of the split vs lump for multiple images is what if you watch a butterfly or cicada emerge over several hours? You might well get interesting things to see that merit different observations and stringing them all into one kind of breaks the “point in time” assumption about observations.
I split this one into four, roughly corresponding to time slices when I paid attention and took photos vs. taking a break, then linked them all in the descriptions:
