Guess the Pest Week #16 Answer:

Lady Beetle Larva
Lady beetles, sometimes referred to as ladybugs or ladybird beetles are ferocious predators and play an important role in reducing pest populations in many crops. Both the adult and larval stage prey on insect pests and are considered one of the “good guys”. They are especially fond of aphids and a single beetle has been reported to consume as many as 5,000 aphids during its lifetime. Finding a lot of lady beetles in your crop is a good indication that you have an aphid infestation, but don’t be too alarmed. Lady beetles will often keep the population in check. For example, in small grains, one lady beetle (adult or larva) per 50-100 aphids is often sufficient to achieve biological control.
