The eggs are said to be laid on or in the nests of bees and wasps where the larvae develop, feeding on the refuse of the nest. The characteristic bee shape and coloration is obviously of advantage here. The other colour form resembles the black and yellow bumble bees. The fly is again shining black, but the abdomen has two bands of brilliant yellow hairs across it and the thorax is similarly clothed. Both forms have shiny wings with dark markings across them. Any visit to an Essex wood would provide these and many other equally fascinating insects, other habitats such as grassland or even the nettle patch in the back garden will produce a wealth of equally interesting species. Ron Allen ********** ESSEX DEER SURVEY About five years ago a survey of the distribution of deer in Essex was started, This venture was sponsored by both the Club and the Essex Naturalists' Trust, Most of the county has now been covered, and fallow deer are common in many areas north of a line joining Brentwood, Chelmsford and Colchester, Fallow deer have been found in very few areas south of this line. Both muntjac and red deer have been recorded from a few scattered areas but there have been no confirmed records of roe, sika or Chinese water deer. Because the records span five years, spot-checks are being carried out to check the older records. The aim is to try to produce a complete survey of the distribution of deer in Essex, which is accurate for 1971. It is hoped that members will assist in completing this survey by sending any records (both old and new) of deer or signs of deer, press reports, hearsay, etc. to me as soon as possible. Offers to assist with the spot-checks of various areas would also be most welcome. These should be sent to: Mr. Donald Chapman, East Lodge, Lanwades Park, Kennett, Newmarket, Suffolk.
