Four new species of Sphecodes bees to add to the record on the lode-hornigsea field system.
- Sphecodes rubicundus
- Sphecodes ephippius
- Sphecodes geoffrellus
- Sphecodes longulus (which is tiny only a few mm long)
- Already recorded is Sphecodes monilicornis
Length 8mm. One of the black and yellow banded Nomada species, N. lathburiana also has red markings on the body.
Around the nesting sites of its host Andrena cineraria.
When to see it
Seen from April to June.
Nomada lathburiana was a Red Data Book species but seems to be fairly frequent, and increasing in numbers along with its host Andrena cineraria, suggesting that its status may be secure.
I have posted info on this bee before .
This species is distributed widely throughout most of the area covered by this Atlas, but is rarely common. It is widespread in Europe; middle and northern latitudes of Asia, and eastwards to Mongolia (Løken 1973).
Status (in Britain only)
This bee is not regarded as being scarce or threatened.
This cuckoo-bee occurs in a wide variety of habitats.
Over-wintered females can be found from late April onwards, males and new females in July to September.
As this bee is parasitic it does not collect pollen, although females eat pollen in order to develop their ovaries. Foraging for pollen for the nest is carried out by the host workers.
During spring the over-wintered, fertilised female B. barbutellus searches for a small nest of the host bumblebee, B. hortorum. It enters the nest and eventually dominates, or kills the host queen. The parasite female then lays eggs which will develop into either males or females of B. barbutellus. All foraging and nest duties are carried out by the host workers. It is likely that this species will also attack B. ruderatus.
Visits are made to a wide variety of flowers.
