Thamnurgus varipes Eichhoff, 1878

on Euphorbia


The female bores a vertical gallery of a few cm in the stem, and deposits some eggs. Also the larvae make galleries in the stem, that sometimes are recognisable from the outside by the greyish-blue colour of coagulated latex. Also pipation and hibernation takes place in the stem. The stem does not show a recognisable swelling but the leaves have turned limp.
