During the transition from early spring to early summer, one might notice a peculiar sight: a spit-like substance nestled within the crevices of plants, grasses, and flowers. Despite its ubiquity, many remain unaware of its origin and purpose.
Behold - the spittle bug house!
The spittle bug, in its nymph stage, precedes the adult froghopper. While froghoppers abound during the summer and fall months, their juvenile form often goes unrecognized. But let's focus on their characteristic spit house.
Is it truly spit? In a sense, yes. Spittle bugs secrete plant juices or sap, which they ingest to craft their unique abode. Resembling human saliva in consistency but slightly denser, this foam serves multiple functions.
Firstly, it provides protection. Concealed within the spit house, the spittle bug remains obscured from view, while its adhesive nature dissuades smaller insects from prying into its bubble-like sanctuary. Secondly, it serves as insulation, shielding the inhabitant from chilly winds and the scorching summer sun. Lastly, it regulates humidity, ensuring the spittle bug remains hydrated and protected from desiccation.
North America hosts approximately 60 spittle bug species, with the Meadow Spittle Bug being the most prevalent. While they can pose a threat to vegetable plants in large numbers, they can be easily dislodged with a gentle hose spray. It's advisable to refrain from harsh chemical interventions due to their potential long-term ecological repercussions on pest and herbicide management.
