And.......Not a cuckoo in sight........!!

Woke up after my night shift to a wet and miserable afternoon.......So where is my Blip coming from today....?? Outside my huge lavender bush is greening up nicely.....Smells fantastic all year around, flower buds just starting to show. It is a insect magnet when in flower, in fact it can buzz alarmingly in full bloom. Anyway at the moment it is covered in cuckoo spit......Not sure if this is a friend or foe.....??
