Ladybird beetles are very common in lettuce crops over summer and you may even find a few on lettuce in your garden or local fruit & veg shop.
If you buy unbagged / loose lettuce, just rinse in cold water to remove any traces of soil or insects.
Vegetable crops attract hundreds of different insects, from beetles and caterpillars to bees and moths.
Only a few of these insects are crop pests and many of the pests are only a problem for a short time.
Most insects are “Good Bugs”: predators, pollinators and parasites of crop pests.
“Good Bugs” include ladybird beetles, hoverflies, midges, lacewings, earwigs, wasps and mites.
