Common thrip

<em>Thrips pini</em> is a small insect in the order Thysanoptera, family Thripidae, recorded from Denmark, Norway, Sweden, and the United States. It is Not Evaluated on the IUCN Red List. As its name suggests, this species is principally associated with pine trees, feeding on the young shoots, buds, and needle bases of <em>Pinus</em> species, where feeding damage can cause discoloration and distortion of foliage. It inhabits coniferous forests and plantations, particularly in northern and temperate regions. Like other thrips species, it is a minute insect, typically 1–2 millimeters in length, with fringed wings. Populations are typically univoltine or bivoltine in northern climates, and overwintering occurs in litter or bark crevices. Diet consists of plant tissue, primarily from pine hosts. The species has limited direct economic significance compared to some other thrips pests, but can contribute to forest health concerns when populations reach high densities. Biological traits such as precise adult body weight, lifespan, and egg output remain poorly documented in standardized scientific assessments.
