The diminutive Strawberry Blossom Weevil (Anthonomus rubi) with its oversized snout (or rostrum to be more correct) can play havoc with strawberries in an incredibly clever way.
The female weevil uses her snout to stab a hole into an unopened flower bud (that’s what she’s doing in the picture above). She then turns round and places an egg right into the hole and into the centre of the flower bud. Not content with that, she will then damage the stem below the bud, cutting off the sap supply.
This results in characteristic unopened flower buds that wither on their stalks. If you look very closely, you can often see the puncture marks on the bud where the weevil made her hole. Inside, will be the developing weevil grub.
These weevils also have a taste for raspberries and blackberries.
