Gravity feed butterfly feeder with mesh pad feeding stations
摘要:
A feeder for butterflies has a reservoir to contain a feeding solution. The neck of the reservoir has a head and at least one feeding station is connected to the head. The feeding station is in fluid communication with the reservoir. A mesh-like pad is disposed in a well in the feeding station so that the butterfly may land on the pad.
