[78] Adults have both winged and wingless forms; in the grass thrips Anaphothrips obscurus , for example, the winged form makes up 90% of the population in spring (in temperate zones), while the wingless form makes up 98% of the population late in the ...
Trombiculid mites are found throughout the world. In Europe and North America, they tend to be more prevalent in the hot and humid regions. In northern Europe, including the British Isles where they are called harvest mites, the species Neotrombicula autumnalis are found during the summer and autumn (in French, harvest mites are called aoûtat because they are common in August [19]).
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally (endothermic), insects must rely on external sources to provide their heat (ectothermic).
However, some thrips, including rose thrips, onion thrips, and western flower thrips, damage plants. They can weaken vegetables and flowers and even spread plant diseases . What Do Thrips Look Like?
Thrips simplex is a tiny insect, measuring 2 mm (0.08 in) long, with a long slender brownish-black body with a pale band at the base of the wings. The larvae are wingless and yellow or orange.

The western flower thrips [Frankliniella occidentalis (Pergande)] is an invasive pest insect in agriculture. This species of thrips is native to the Southwestern United States [1] but has spread to other continents, including Europe, Australia (where it was identified in May 1993 [1]), and South America via transport of infested plant material.
Scirtothrips dorsalis, the chilli thrips [derivation 1] or yellow tea thrips, is an extremely successful invasive species of pest-thrips [1] which has expanded rapidly from Asia over the last twenty years, and is gradually achieving a global distribution. It has most recently been reported in St. Vincent (2004) Florida (2005), Texas (2006), and ...
