tulip-tree silkmoth & promethea Moth 

This beautiful orange beauty is a female Tulip-tree Silkmoth, one of our large silkmoth species. 

This is a male Tulip-tree Silkmoth. Males are darker than the females. They have a nice chocolate brown color.  Found at my black lights on June 7, 2024. 

Another view of the Promethea Moth (same individual as above). Promethea Moths tend to be more reddish in color and smaller in size than a Tulip-tree Silkmoth. Male Promethea Moths are very dark brown and do not usually come to lights. 

This is a female Promethea Moth, the only one I have ever found. She came to my black lights on May 2, 2024. Note that the white spots on the upper wings are smaller and thinner than the white bars on the hindwings. This is one of the more reliable ways to tell the two species apart. Promethea Moths usually have the upper spots on their forewings either absent or reduced in size compared to the lower spots. 

Another Tulip-tree Silkmoth, found at my lights on June 3, 2022. This individual had damaged wings, possibly from a bird attack. 

Another female Tulip-tree Silkmoth. This species is very similar to the less common Promethea Moth (below). Note that this Tulip-tree Silkmoth is more orange than the red Promethea Moth below. Also, note that the white chevrons on this Tulip-tree Silkmoth's upper wings are larger than the white marks on the lower wings. This is usually reversed in the Promethea Moth. 

I have found a few Tulip-tree Silkmoths at my lights from May through August. I find more females than males.
