Bubble blower
21st June 2010, Monday
Cuckoo spit is now abundant in some grassland. It is produced by the nymphs of Froghoppers as a protective structure, made from the watery sap that it feeds on. If you carefully wipe away the bubbles you will find the nymph.
If you watch carefully you will see the animal remaking its frothy security banklet by blowing bubbles from its rear end!
