In my quest to become an expert in Oecanthinae....I figured I need to start from the egg stage. I realize this first year will be more of a learning experience than a period of gathering information -- and that none of my babies may survive until adulthood. Today, however, I have made an interesting discovery. After competing with ants for two small gatherings of some kind of black aphids on thistle-- and setting them up in the babies habitat -- I noticed three of the Oecanthinae nymphs were nibbling on cat treats ! I'm tempted to take the aphids out, cuz one group looks like they could eat the tiny Oecanthinae.
