Plant Parasites of Europe

leafminers, galls and fungi

Synanthedon formicaeformis

Synanthedon formicaeformis (Esper, 1783)

red-tipped clearwing

on Populus, Salix

gall

Like in most Sesiidae, the larva tunnels in wood that previously has been damaged, either by mechanical causes or by other wood-boring larvae, or in cankers caused by fungi or bacteria. Sometimes the larva makes a circular gallery around the branch, causing then a pear-shaped swelling. Often the exuvium remains for a long time protruding from the exit opening.

host plants

Salicaceae, oligophagous

Populus tremula; Salix alba, aurita, caprea, cinerea, x fragilis, purpurea, repens, x smithiana, triandra, viminalis.

The occurrence on poplar probably is exceptional. Redfern & Shirley state that Salix viminalis is the primary host; this is not confirmed by other sources

larva, pupa

Larva and pupa are extensively described by Bąkowski.

synonyms

Sesia formicaeformis.
