This heavy duty hummingbird/meal worm feeder will give the versatility to use as feeder all year long. This set comes with two black metal spheres which are 6 inches wide x 7-1/2 inches tall and has a 4 inch round center to hold the recycled glass cup and red top glass hummingbird feeder lid. The metal has a hook at the top so you can hang it wherever and however you choose. You can hang multiple feeders below each other by hooking them together. (see pictures) You can use this as a hummingbird feeder in the summer, when you have an abundance of hummers and then remove the red glass top to expose a cup to hold meal worms other times of the year. This piece can also be used as a terrarium...both outdoors or indoors. We have shown a picture of this for you to envision the versatility and use of this piece.
