Coccinellidae November depending on location and weather conditions. Homes or other buildings near fields or woods are particularly prone to infestation. After an abnormally long period of hot, dry weather in the summer of 1976 in the UK, a marked increase in the aphid population was followed by a "plague" of ladybirds, with many reports of people being bitten as the supply of aphids dwindled. The presence of coccinellids in grape harvests can cause ladybird taint in wines produced from the grapes. "Harmonia axyridis" (the harlequin ladybird) is an example of how an animal might be partly welcome and partly harmful.
Evolution of insects one that offers an explanation for the problems of why presumably aquatic animals evolved in the direction they did. Leaping and arboreal insects seems like a good explanation for this evolutionary process for several reasons. Because early winged insects were lacking the sophisticated wing folding mechanism of neopterous insects, they must have lived in the open and not been able to hide or search for food under leaves, in cracks, under rocks and other such confined spaces. In these old forests there weren't many open places where insects with huge structures on their back could have lived without experiencing huge
