Haematoloma dorsata

Froghopper Haematoloma dorsata

Description

Haematoloma dorsata is a froghopper species primarily found in Mediterranean regions but has expanded its range across parts of Europe, including the Netherlands, France, Belgium, and Switzerland. The insect targets several conifers, particularly Pinus species such as Scots pine (Pinus sylvestris), black pine (Pinus nigra), and Aleppo pine (Pinus halepensis), among others. Adults feed on conifer needles by piercing them with their sucking mouthparts, which causes transverse rows of yellow to brown rings. Over time, needles may turn brown and fall off. The larvae, covered in a frothy secretion for protection, feed on the roots of grasses, where they also overwinter. This species has one generation per year, with adults emerging from spring to early summer.
