Just like a caterpillar pupates in a cocoon to turn into a butterfly, the thrips nymph evolves into a full adult during the pupa phase. Where to find thrips prepupa and pupa. Thrips will often travel to the ground to pupate. They hide in leaf debris, soil, and mulch. In fall, this is how most thrips prepare for winter.

Thrips (order Thysanoptera) are minute (mostly 1 mm (0.04 in) long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Entomologists have described approximately 7,700 species.

Thrips are tiny insects about as fat as a sewing needle that dine on many plants worldwide. Also known as thysanoptera or thunderflies, thrips are sucking insects that can cause some damage to plants.

Some species enclose the pupa in a cocoon on the ground or on the host plant. The winged adult thrips emerge from the cocoon or pupal stage. Outdoors, generations may occur every two to three weeks, but the largest populations are present from late spring to midsummer.

Although Thysanoptera are hemimetabolous, many species undergo an extended metamorphosis in which the final immature stage is quiescent, non-feeding, and sometimes even enclosed in a silken cocoon.

Thrips are generally small insects (under 3 mm). Many species are parthenogenetic. Although Thysanoptera have gradual metamorphosis, many species undergo an extended metamorphosis in which the final immature stage is quiescent, non-feeding, and sometimes even enclosed in a silken cocoon. body segments: cylindrical.

Thrips typically develop into mature adults within 20 days. Upon emerging from their cocoons, young thrips feed on the plants on which they were initially deposited. While young stages are similar in appearance to their adult counterparts, they do not have wings and move from plant to plant by crawling until their wings develop.

Feb 2, 2025 · Thrips are tiny insects that can damage plants. Most thrips are less than 1/20 of an inch long, so they’re not easy to spot with the naked eye. Instead of spotting the thrips themselves,...

Thrips, order Thysanoptera, are tiny, slender insects with fringed wings. They feed by puncturing the epidermal (outer) layer of host tissue and sucking out the cell contents, which results in stippling, discolored flecking, or silvering of the leaf surface. Thrips feeding is usually accompanied by black varnishlike flecks of frass (excrement).

Thrips populations increase rapidly under hot, arid conditions, leading to economic crop losses. Yield reduction, from smaller bulb size, is the primary crop loss caused by onion thrips.
