Tarsi are yellowish-brown and the fore tarsi have an apical tooth adapted for digging.
Wings are long, narrow, and fringed with long hairs. The fore wings are brown and the hind wings are pale. Only female pear thrips are known to occur in North America. Eggs are laid mainly in the petioles of blossoms and leaves as soon as buds open. Small brown scars develop soon after eggs are laid.
