What field hero can eat 135 aphids in 24 hours?
Answer: Thirteenspotted lady beetle
A study in Manitoba on lady beetles feeding on different species of aphids on cereal crops found that the number of aphids consumed depended on the species of lady beetle and the species of aphid being consumed. Adults of the thirteenspotted lady beetle, one of the more common species in Manitoba, each consumed between 110 and 160 aphids on average in 24 hours, depending on the species of aphid they were feeding on.
