I haven't seen any yet in the Akron area, but I did see a Red Admiral butterfly! The hummers will probably be back in the next week or two. I have a mantis eggcase too. I think they hatch sometime in May, when the nights aren't as cold. Unless you do what I did once as a kid; I left one in the living room and the eggs hatched in March!! My parents were not very pleased!

I live in Columbus and have only seen a hummer once in 8 years. I live in the city with a golf course nearby. I do have a ton of praying mantis with nests all around my garden and don't expect to see them for several weeks yet.

I haven't seen any hummers yet. I start to see them in my yard late May or Early June when they come to feast on the nector of the red flowers of my heuchera (until the bunnies eat them!)

I saw a hummer yesterday in Richfield(Summit County)! She was hovering by the suet.
