缨翅目（Thysanoptera）是昆虫纲的一目，通称为蓟马。

小型而细长的昆虫，体型小约1mm左右，一般黄褐或黑色；眼睛发达；翅膀狭长，具有少数或无翅脉，翅缘扁长，不少种类的翅膀外缘有排列整齐的长细毛，所以称为缨翅目；尾缺须。变态为渐进变态。

蓟马有左右不对称的锉吸式口器，食性相当广泛，包括动物、植物与花粉、蕈类等等，有不少的种类是重要的农业害虫，不过也有些种类猎食小型昆虫或者螨类，目前纪录约有5000多种。

Thrips (order Thysanoptera) are minute, slender insects with fringed wings (thus the scientific name, from the Greek θύσανος thysanos ("fringe") + πτερόν pteron ("wing")). Other common names for thrips include thunderflies, thunderbugs, storm flies, thunderblights, storm bugs, corn flies and corn lice. Thrips species feed on a large variety of plants and animals by puncturing them and sucking up the contents. A large number of thrips species are considered pests, because they feed on plants with commercial value. Some species of thrips feed on other insects or mites and are considered beneficial, while some feed on fungal spores or pollen. Approximately 6,000 species have been described. Thrips are generally tiny (1 mm long or less) and are not good flyers , although they can be carried long distances by the wind. In the right conditions, like indoor grow rooms or greenhouses, many species can exponentially increase in population size and form large swarms because of a lack of natural predators, making them an irritation to humans.
