Dear Dr. Rudman,
Regarding your question about the color of the digestive gland in Favorinus elenalexiae .. I have only seen a couple redder specimens and one that looked more brown than pink, but the one in the picture is the color I usually find. Unfortunately I cannot relate it to the diet since I do not have records for that.

Thanks Ali,
It is interesting how the digestive gland of some species, such as Favorinus japonicus, seems to be quite dependent on the colour of the eggs they eat, and yet in others the colour seems independent of the colour of their food. You would think your animal, eating white eggs, would have a whitish coloured digestive gland, and yet it appears to be red or bright pink.
Cheers,
Bill Rudman
