Its early june,my adult ash trees leaves are falling like rain. The leaves are green but along the vain is an orange colored capsule shaped what looks like an egg sack.Breaking it open shows no larve that I was expecting. Our local tree guy doesn`t know. I can`t seem to find anything close. The tree never did that before. Thanks, Joe Vecchione
