Common thrip

<em>Thrips trehernei</em> is a species of thrips in the order Thysanoptera, family Thripidae, recorded from Denmark, Norway, Sweden, and the United States. It is Not Evaluated on the IUCN Red List. Relatively little is known about the ecology and biology of this species compared to economically significant thrips. Like other thysanopterans, it is likely a plant feeder, inhabiting flowers, foliage, or bark surfaces of host plants in temperate regions where it occurs. The genus <em>Thrips</em> is large and diverse, with many species associated with specific plant hosts or habitats. This species has been recorded from Scandinavian and North American localities, suggesting a trans-Atlantic distribution, possibly facilitated through plant trade or natural dispersal. Adult thrips are minute insects typically measuring 1–2 millimeters in length, with characteristically fringed wings. Biological traits such as precise host plant associations, body weight, lifespan, reproductive output, and generation time remain poorly documented in standardized scientific assessments for <em>Thrips trehernei</em> specifically.
