Postman

The Postman butterfly has large long wings with an orange stripe down each forewing. It is poisonous and has red patterns on its wings. They tend to look similar to the species Heliconius erato. Two features found on the underside help to distinguish H. erato from H. melpomene—H. erato has four red dots where the wing attaches to the thorax while H. melpomene has three and the yellowish white stripe on the underside reaches the margin of the hindwing in H. erato but ends before reaching in melpomene.
