Callicera spinolae Rondani and C. aurata (Rossi)
Further research has revealed more information about the Red Data Book 1 hoverfly Callicera
spinolae (see plate 6) recorded new to Essex from Hylands Park, near Chelmsford in 2001 since
the publication of my note in the Essex Field Club Newsletter last January (Hanson 2002).
In my note I indicated this fly had been recorded recently only from four sites in the UK, all in East
Anglia, one of which was Hylands Park. In fact at one of the Cambridgeshire sites it was thought to
be extinct by 1983 and at one other site it was reduced to using two trees, one of which was blown
down in the winter of 1994/5. At the third site, in Suffolk, the record is a sight record of a single
adult (Ball & Morris 2000). Graham Rotheray (pers. comm.) indicated that sight records can be
unreliable because the flight period of C. spinolae could overlap with the related species Callicera
aurata which has also been recorded from Essex only recently (Ismay 2000). It was found in
Epping Forest in 1999, taken in a malaise trap placed over a recently dead Beech tree. C. aurata is
also a very rare species in Britain, accorded RDB3 status.
