Distribution.
From southern Europe (northern
Spain
,
Andorra
, southern
France
,
Italy
including
Sardinia
and
Sicilia
) over southeastern Europe (
Croatia
,
Macedonia
,
Bulgaria
,
Romania
,
Moldova
) to eastern
Turkey
and the Caucasus (
Armenia
); from western Europe (southernmost
United Kingdom
,
France
,
Belgium
,
Netherlands
) over central Europe (
Luxembourg
,
Germany
,
Poland
, Czech Republique,
Slovakia
,
Switzerland
,
Liechtenstein
,
Austria
,
Slovenia
,
Hungary
), northern Europe (southernmost
Norway
, southernmost
Sweden
) and eastern Europe (
Ukraine
,
Russia
) to central Asia (
Kazakhstan
,
Kyrgyzstan
) and the Russian
Khakassia
republic of eastern Siberia. The species seems to be absent from most of the Iberian Peninsula as well as from
Greece
. There is a single male from
Crete
(Pass near Pinakino,
19.4.1986
, leg. W. Vöth, Oberösterreichisches Landesmuseum Linz), which might have been mislabelled as no other specimens have ever been recorded from this well explored Greek island. The westernmost record is from
Pembrokeshire
in southwestern
Wales
, the northernmost from
Oslo
province in southern
Norway
, the southernmost from Güragaç in southern
Konya province
of
Turkey
and the easternmost from Shira lake in the
Khakassia
republic of
Russia
.
Pollen hosts.
Oligolectic on
Asteraceae
(
Westrich 1989
;
Müller 1994
). Among the
Asteraceae
, species of the
Asteroideae
(e.g.
Anthemis
,
Aster
,
Buphthalmum
,
Inula
,
Senecio
), Carduoideae (e.g.
Carduus
,
Centaurea
,
Cirsium
) and
Cichorioideae
(e.g.
Cichorium
,
Crepis
,
Hieracium
,
Leontodon
,
Picris
,
Tragopogon
) are exploited for pollen. On the
Asteroideae
, which is probably the most important pollen host taxon among the
Asteraceae
subfamilies (
Fig. 1
), the females take up pollen from the surface of the capitulum directly into their scopa by rapidly moving the metasoma up and down (“abdominal drumming” sensu Cane 2017). On Carduoideae und
Cichorioideae
, they use their hind legs to direct the pollen-bearing flower structures under the seesawing metasoma. To provision one brood cell, the entire pollen content of about four flower heads of
Buphthalmum salicifolium
is needed (
Müller
et al
. 2006
).
Nesting biology.
Nesting site
: The nests are built in empty snail shells of small to medium size (
Fig. 5, 6
) e.g.
Cepaea
,
Cernuella
,
Fruticicola
,
Helicella
,
Pomatias
,
Xerolenta
,
Zebrina
and occasionally also young shells of
Helix
(
Müller 1994
)
.
Nest architecture
: The nests contain 1–3, mostly 2 brood cells, which are separated from each other by partitions consisting of leaf pulp, e.g. from
Potentilla
or
Sanguisorba
(
Müller 1994
)
. There is no basal wall that seals the innermost brood cell against the rear end of the nest. The shells are sealed at their opening with an additional wall of leaf pulp. There is an empty vestibule of varying length between nest plug and outermost cell partition. The latter probably acts as main barrier against predators or parasites as it is distinctly more robust than the other cell partitions and the nest plug, needing more than 30 flights with leaf pulp for its construction.
Nesting cycle
: On average, about 30 foraging bouts are needed to provision one brood cell, which takes about 12.5 h under good weather conditions (
Müller 1994
). After having sealed the shell, the female crawls upside down under her nest and turns it with her legs so that the shell opening is directed tightly towards the ground (
Fig. 6
), which might possibly provide some protection against inclement weather. Under good conditions, a female constructs up to 20 brood cells during her flight period, which lasts maximally 10–11 weeks. Interestingly, the females regularly control their nests up to four weeks after they have sealed them to repair holes and cracks in the nest plug with newly collected leaf pulp.
Osmia spinulosa
overwinters as a prepupa in a self-spun cocoon within the brood cell. It has one generation per year. However, it seems to be a parsivoltine species since about half of all larvae that emerged from the brood cells were found to undergo metamorphosis only after the second hibernation.
Brood parasites
: The megachilid bee species
Stelis odontopyga
develops as cleptoparasite in the nests of
O
.
spinulosa
(
Noskiewicz 1925
; Blüthgen 1926). Additional confirmed brood parasites are
Chrysura cuprea
(Rossi)
and
C
.
trimaculata
(Förster) (Chrysididae)
,
Anthrax aethiops
(Fabricius) (Bombyliidae)
,
Melittobia acasta
(Walker) (Eulophidae)
,
Pteromalus apum
(Retzius)
and
P
.
venustus
Statz (Pteromalidae)
(
Kunz 1994
;
Müller 1994
; BWARS 2013).
Behaviour.
Male mating behaviour
: The males occupy small home ranges, to which they adhere during their entire flight period, which lasts maximally 5–6 weeks (
Müller 1994
). Within these home ranges, they search for females by patrolling
Asteraceae
flower heads along more or less fixed circular flight routes in a rapid flight, which is interrupted by short resting periods on the ground. Home ranges and flight routes are never defended against conspecifics but instead often widely overlap.
Sleeping places
: The males sleep singly or in small groups within empty snail shells as do females that have not yet started their nesting activities (
Müller 1994
). Nesting females pass the night or periods of bad weather within their nests.
