Eastern Dappled White

Euchloe ausonia


Euchloe ausonia on Sinapis arvensis flowers. Both species are common and Sinapis arvensis is the first to bloom in vast areas early on, even in the winter. Euchloe ausonia adjusts its color to this tide of yellow.


The 4th photo -of Pontia edusa-, is to show the similarities and differences between the two species and comes from my 2018 spotting:

Thank you Daniele and PN for the SOTD!

Nature here in the temperate south has already begun to wake up, despite the heavy winter we had this year. I look forward to interesting spottings!

Great series of images Tania! I also like the added image of Pontia edusa for comparison; very useful. You could even add Pontia edusa in your tags.
And congratulations, this is our Spotting of the Day:

"We're feeling the first signs of spring in the Northern Hemisphere with this stunning Eastern Dappled White (Euchloe ausonia) as our Spotting of the Day! This species and its Western counterpart Euchloe crameri can't be distinguished by external characteristics alone, but can set apart by geographical distribution. In most of its range the Eastern Dappled White comes in two broods, with adults seen from early spring. The larvae feed on the flowers and young fruits of several plants including Sinapis arvensis (wild mustard), pictured here with the adult butterfly.
This year our Best Wildife photo competition focuses on interaction between species: check it out! "

Thank you Sergio!

What an awesome butterfly, and a very nice photo too. Congratulations.

Thanks Brian. You' re right to mention Euchloe ausonides and I've just corrected the species name.

Brian38 a year ago

Stunning pictures Tania! I'm really glad you mentioned its ability to adjust its color. I've observed the same ability with Euchloe ausonides (Large marble butterfly).
