From: Spittlebugs produce foam as a thermoregulatory adaptation
The foam promotes insect thermal protection. Conventional and corresponding infrared photographs of the foam produced by Mahanarva fimbriolata nymphs and of their surroundings in a sugarcane field in Piracicaba, São Paulo, Brazil, at 13h00 on a hot summer’s day. The photographs show the importance of the foam to maintaining the microhabitat temperature lower than the surrounding temperature.
