The apterae are dark greyish-green covered in wax meal giving a light bluish-grey appearance. The last rostral segment is very short and stumpy with a short tip.  The body length is 1.2 to 2.5 mm.

They are found on numerous species of Pines (Pinus spp.), especially on young Pinus sylvestris, forming dense colonies in rows along the previous year's needles. 

Oviparae and alate males occur in October-December, but in years with mild winters colonies may persist through to the next year. Apterae of Schizolachnus pineti can be found on pines all year round providing the winter is not too severe.

True status in Britain is difficult to determine due to lack of records but it is probably fairly frequent and widespread.

Status in Leicestershire and Rutland not known.
