Monarch Caterpillar All Yellow

Does anyone know if this Cat is healthy? It’s all yellow with even its face!
***update!***the cat was molting! Just slower than the others, it is still paler than the others but has very thin black lines. Thank you for all the advice!

color variation can be attributed to temperature or light exposure: Solensky and Larkin, 2003

so this one is just fine.

Oh good I’m so glad! Thank you!

check to see if it changes, it could be a fresh molt


I was wondering the same thing after making this observation.

If it doesn’t color up in a bit, keep an eye on that one. I’d be curious to see if there’s any chance it’s some sort of pigment issue that might result in a neat butterfly.
