2nd June - Does the Cuckoo spit?

June is upon us and the days are increasingly longer, providing more time for countryside walks. On a walk to the castle my musical accompaniment was that of Skylarks, Song thrushes and the enchanting melodic tunes of the Blackbird, while my nostrils were pleasantly assaulted by the heady perfume of flowering Honeysuckle. On the way down I noted Sheep's sorrel and Dog rose in flower.

Also of note was the first Cuckoo spit of the year. This strange foam seems to be on many plants and grass at this time of year. Is it really the result of a phlegmy cuckoo? Well no. Cuckoo spit is basically plant sap that has been ingested by the larva within. It forces air into the sap and then squeezes the aerated bubbly foam out of its bottom. In the middle of the foamy mass you would find a Froghopper nymph - the larva of the adult Froghopper aka spittlebug. Froghoppers have extraordinary jumping abilities helping them evade predators. The nymph however cannot jump so the foam protects it and keeps it moist.

Down by the castle mere two Mute swans drifted serenely while all around them a mixed flock of Swallows, House and Sand martins swooped low over the water picking up emerging insects. Also joining the feeding frenzy were three Daubenton's bats and several Pipistrelle bats. An entertaining end to the day.
