Hawaii a collection of over 5000 specimens held only 5 males in total. Some collections over the years from France, Japan, Taiwan and India have had no reported males at all. One study of the literature published in 1990 suggested a correlation between longitude and male population number, with the higher male counts occurring in the
Western hemisphere.

In some populations, nearly all onion thrips are female, and males are very rare. The adult onion thrips is some 1 to 1.3 mm (0.04 to 0.05 in) long. The body is some shade of yellow, yellowish-brown or brown; the antennae have seven segments, the wings are well-developed and females have an

The onion thrips is the most serious insect pest attacking onion crops in the tropics. The thrips rasp and pierce the surface of the plant with their mouthparts, mostly choosing young plant growth. They then add digestive juices and suck up the fluids that seep from the wounds. As the plant part

In populations from different areas, the ratio of males to females varies. A male to female ratio as high as 1 male to 2 females has been recorded from
Central Spain, and 1 male to 6 females in Colorado. In contrast, counts as low as 1 male to 300 females have been recorded from Sudan, and in
