Swammerdamia caesiella is a moth of the family Yponomeutidae. It is found from most of Europe to Japan. It is also present in North America, [2] where it is possibly an introduced species. [3]
The wingspan is 9–13 mm. The head is white. The thorax is white, sometimes anteriorly fuscous-sprinkled. Forewings are white, irregularly irrorated with fuscous; some longitudinal series of blackish dots; antemedian dark fuscous fascia reduced to two spots, discal and dorsal; two white spots on costa posteriorly, separated by a dark fuscous spot; cilia coppery-tinged, with two dark purplish-fuscons lines. Hindwings are pale fuscous. The larva is reddish-brown; dorsal line broad, paler, becoming indistinct posteriorly; spiracular broad, yellowish-white; head pale yellow-ochreous. [4]
They are on wing from May to June and again in August in two generations per year. [5]
The larvae feed on Betula species.
