This species is commonly found on bushes and on the flowers and leaves of plants. They can cause some damage to these plants by sucking the juices from them. After enough meals, the Leafhopper can emit bubbles of liquid waste from its abdomen. This liquid retains some of the sweetness from the plant's juice and is very attractive to a variety of other insects like wasps and flies.
Here is a YouTube video of the leafhopper emitting bubbles.
