Here is a picture of a C. eurytheme (female) which I collected a few years ago. Hopefully, Bobw will see this... This specimen ranks as the yellow-ist version of the "Orange Sulphur" which I have ever personally encountered. Over here, C. eurytheme may be the ubiquitous species of the eastern US (along with philodice). However, it still pays to stay sharp whilst in a field of it; as odd ones like this still make it curiously interesting !  |

Some colias do have very yellow forms to their normally orange colour. There is a form of Colias crocea from the Azores called cremonae which is completely lacking the orange pigment and is outstanding.  |

After looking at your yellow erytheme female, I took a look at one that I had in my philodice box and now am wondering is it philodice or erythema. It does have a very orange spot on the hindwing as well as a wide forewing border. Thoughts?  |

And here is a male that looks like philodice with some orange shading on the forewings, I assume a likely hybrid?  |

I will post photos later to have an expert determination. |

I also have a male very much like the one in your photo !  The forewing spotting of my female is I believe typical of C. eurytheme. However, your looks more like a C. philodice female to me since the forewing spot pattern is different. These male hybridized examples are mighty tough to discern indeed and this is not the only one like this I've run across... That's why on these sulphurs one must really look closely at every one you can in a field ! |

Is there any reliable feature to distinguish females of C. philodice and eurytheme. I have doubts for some of my specimens.
