This Queen butterfly was photographed at the ‘Wall’ in Mission Texas. She was nectaring at a famous, much visited perennial garden set at the entrance wall to a popular development of homes.
The image of a pair of coupled Monarch butterflies (he easily seen here) was taken in the perennial gardens of the National Butterfly Center, also in Mission, Texas.
Both are Danaus butterflies, both relying on native milkweed plants as their hostplants.
Here in Eatonton, Georgia we have Monarchs visiting daily, to nectar on our natives and Mexican Sunflower, and to deposit their eggs on our several species of milkweed.
A visit from a Queen, here in central Georgia, is possible, but unlikely.
The 3rd image is a Danaus butterfly, the Plain Tiger, halfway around the world, in Mishmarot, Israel. A male I think.
Danaus butterflies have much in common, and then again, vary much.
