In the UK there is quite strong regional differentiation, with S.
philantha and fatarum being strongly northern and western but also
found in heathlands in southern England. S. potentillae is confined
to Culm grassland in the SW. S. taeniata and S. batava are
differentiated on habitat with S. taeniata more closely associated
with grasslands and S. batava with ericaceous scrub. There are few
records of S. virgata but this too seems to be a heathland species.
There remains a question mark for S. interrupta but my feeling is
that it is more a northern and western species. No idea for S.
bankowski!<br>

See chapter 10 pp. 311-318 for Sphaerophoria. These species
accounts are based on the collective field experiences of many

<div dir="auto">In Poland S. virgata is forest species, and
rare. S. scripta is present on all possible types of meadows
incl. ruderal areas, being sympatric with S. taeniata and
S. batava on e.g. forest glades and "good open areas",
especially on coasts an along rivers - many times I gathered
longer series of all three. S.philantha is extremely rare.
S.interrupta is very rare.</div>
