The adult stage can be reached in around 8–15 days; adults can live for around 45 days. [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 ...
The green peach aphid, Myzus persicae, is a vector for more than 110 plant viruses. Cotton aphids (Aphis gossypii) often infect sugarcane, papaya and peanuts with viruses.

Just like other species of thrips, their lifecycle consists of egg development, two nymphal stages, a non-feeding propupal stage and pupal stage.

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. These thrips live hidden inside the leaf and flower sheaths of their host plants where they suck sap, usually occurring in groups.
In order to protect their eggs, thrips insert their eggs into various types of plant tissue. Eggs can be found in the stems, leaves, or flowers of plants. [8] Thrips hatch in 2–3 days and complete their life cycle in 20–30 days. [2] Adult thrips feed on the flower bud, stem and leaf parts of the plant. [8]
