COVID-19 is not the only problem we face in these troubled times.
The scourge of the citrus tree, the Fruit-piercing Moth is upon us.
If your citrus is found on the ground, this moth is probably the cause.
These not-so-little blighters attacked my lemonade, then, when there were no more, moved on to the adjacent orange. They are not so keen on the less ripe lemons. They've now either found someone else's citrus or don't like the cold, but the damage is done.
