Hemaris tityus, the narrow-bordered bee hawk-moth, is a moth of the family Sphingidae which is native to the Palearctic. It has a wide range, from Ireland across temperate Europe to the Ural Mountains, western Siberia, Novosibirsk and the Altai. It is also known from the Tian Shan eastwards across Mongolia to north-eastern China and southwards to Tibet. There is a separate population found from Turkey to northern Iran.
It appears in May and June and is a lively day-flier (unlike most other sphingids), generally active from mid-morning to mid-afternoon. It frequents marshy woodland and damp moorland, and has a wide distribution across temperate Europe and Western Asia, but is generally quite scarce. The larvae feed on devil's-bit scabious (Succisa pratensis) and field scabious (Knautia arvensis).
It is distinguished from H. fuciformis by the narrow band of scaling along the outer wing margin, and the forewing's undivided discal cell. It has a wingspan of 40–50 millimetres (1.6–2.0 in). It is one of two similar species of sphingid moth occurring in Britain that closely mimic a bumblebee. Wikipedia →

Rare
Under 5% of wildlife watchers report a Narrow-Bordered Bee Hawkmoth sighting in Vienna on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 795th most-seen of the 1406 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 Narrow-Bordered Bee Hawkmoth in Vienna on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Narrow-Bordered Bee Hawkmoth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Narrow-Bordered Bee Hawkmoth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Narrow-Bordered Bee Hawkmoth is recorded against all the insects logged in Vienna (12 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.
