Phrynus whitei (mini beasts) has one red spot?

[amblys]

So I checked up on my amblypygi and noticed they have one little red spot on them now? Should I be worried!
I know whitei normally have spots but do they show up and I wasn’t excavating mine to get them?

It's just a piece of dirt

The Whitei that originated from @wizentrop do not have the characteristic spots at any point throughout their lives

Yes, it is possible that those came from my Honduras stock, they are black without eyespots.
