Mid summer can be a time for a couple of creatures that are determined to make certain plants look untidy.

 

Sawfly larvae love to feed on Solomons Seal polygonatum x hybridum. They start by making holes in the leaves but can strip a plant to bear stalks and untidy veins in no time. Check beneath the leaves and pick off any caterpillar like creatures. A pyrethrum based insecticide will also work to control sawfly.

 

The leafcutter bee is more a friend than a foe even though they can make you rose leaves look like they have been chewed around the edges. Circles of leaf are cut from leaves and carted away to form cocoons to surround eggs. Damage to plants is unlikely to kill the plant. These bees are great pollinators and are worth leaving alone to get on with being part of your gardens ecology.

Flea beetles can speckle rocket and brassica leaves and leave holes of different sizes. In the main the leaves are still edible and as the insects are so small it is hard to spot them. You can grow under fleece if the problem is severe.
