Synanthedon formicaeformis, the red-tipped clearwing, is a moth of the family Sesiidae and can be found in all of Europe, the eastern Palearctic realm, and the Near East. The larvae sometimes form pear-shaped galls on willows (Salix spp). It was first described by Eugenius Johann Christoph Esper in 1783.
The eggs are laid in axils, bark crevices or stump edges of Salix species from the end of May to late-July. The larvae feed inside the stems of various Salix species, including Salix viminalis. According to Heath and Emmet (1985) the larvae give little external sign apart from a slight browning, and at the edge of a broken stem frass may be seen. The larvae feed between the wood and the bark and can be found in their tunnels when the bark is peeled back. When there are galls they can be pear-shaped, or a ″peculiar shape″ with the ″diameter of the stem above the gall greater than that below, which continues for some distance″. Galls can be similar to the sallow clearwing (Synanthedon flaviventris).
The pupa is 12–14 mm long and does not make a cocoon. The emergence holes have a diameter of circa 2.5 mm and before pupation can be hidden by a thin cap. The exuviae can... Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-Tipped Clearwing Moth sighting in Saint Petersburg on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 332nd most-seen of the 448 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Red-Tipped Clearwing Moth in Saint Petersburg on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Red-Tipped Clearwing Moth sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
3rd of 3
Of the 3 cities where we can rate Red-Tipped Clearwing Moth sightings, Saint Petersburg ranks 3rd at under 5%. The best odds are in Manchester (United Kingdom, about 10%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Red-Tipped Clearwing Moth is recorded against all the insects logged in Saint Petersburg (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
