There are several hundred species of neotropical green moths in the family Geometridae, subfamily Geometrinae. Many have a blue-green or yellow-green colour to their wings hence the common name "emerald moths". This moth is probably in the genus "Synchlora". Photographed in the morning at a light trap.
These two different moth species in the family Erebidae would not normally associate in this way. A light trap the night before this photo was taken brought them together.
