On day three of National Tree Week, we are sharing the signs of the oak apple gall wasp (biorhiza pallida) that Naomi stumbled upon recently 🍎 This is not an *actual* apple though. These apple-like galls appear on oak twigs from May/June time after female oak apple-like gall wasps lay their eggs in an oak leaf bud. The chemicals released by their hatching larvae signals to the oak to grow the gall (the tissue that encapsulates the insects and feeds and protects them as they develop.) These lovely little galls house many chambers in which the larvae develops, the adults then eat their way out in June/July. There are over 30 gall wasp species in the UK, but no need to worry as they do not cause any significant harm or damage. Join us again tomorrow for our next tale of trees 🌳🌲🌴 #NationalTreeWeek #Sustainability #TylerGrange #Environment #Biodiversity #ClimateAction #GreenFuture #EnvrionmentalConsultancy
