Wingless adults do exist, but occur primarily during the winter. The largest thrips family, Thripidae, also contains the highest number of economically important thrips species. Bulbs, leaves, and flowers are all subject to thrips attack. Common thrips are not easily distinguished from other thrips families. Because of their minute size, species identification in the field is not practical.
Mites are very tiny arthropods closely related to insects.
Their size and frequent similarity in shape and color make it difficult to distinguish between species. Not all mites found on field crops cause damage to plants. Some are predaceous and help control the harmful mite species. In this respect it is useful to know which species are present. In most states, the agricultural extension service offers a pest identification service or reference to one.
