DISTRIBUTION:

The Automeris io texana moth flies in Texas.

Most people regard io texana as synonymous with nominate io.

The spring broods of nominate Automeris io io often show dark brown patches along the inner margin of the forewing. This is true of specimens taken in southern Florida and Texas. Other forewing markings also tend to be accentuated. The forewings of the female are often dark brown with less maculation.
