The on-going computerisation of Worcs BRC records is enabling maps to be prepared for some smaller groups so giving an idea of the county status of species, or, more frequently, showing how short of records we are. Following on from Gary Farmerís articles in Worcestershire Record No 7 November 1999 maps were prepared (by Martyn Hodgson) for Orthoptera - grasshoppers and crickets - and they are printed in this issue. We were quite shocked to see how few records we have for this group, and how much of the county is blank. The shortage of records is unfortunate because some species have probably declined with the loss of unimproved grasslands, rough grassland, and the increase in mangled road verges, and general countryside tidiness
As the Worcestershire species are fairly easily identified, especially as late summer adults, so we think we should all try to help rectify the sad state of Worcestershire grasshopper and cricket records. We have therefore declared 2000 as the YEAR OF THE GRASSHOPPER and request that you hop our there and get some records!
To help you in this Gary has prepared a simplified key for the Worcestershire species which is printed in this issue. This excludes all the unlikely species and makes identification much simpler than following keys covering all national species. The availability of this key removes most of your excuses!
Also, Orthoptera are good subjects for photography because they are quite large and sit still if you approach with care. So if you have become tired of taking endless photos of butterflies and dragonflies we suggest you now concentrate of crickets and grasshoppers. If you get good photos Gary will try and identify the subjects for you, but please be sure to record date and exact location.
Also, if you need to fill the void created by the end of the field work for the butterfly atlas, fill it with grasshoppers and crickets! All those nice butterfly places are probably also good for orthoptera.
To help still further Gary is running an outdoor tutorial near Grafton Wood on 12th August. If you would like to attend please complete the enclosed booking form and send it to Gary so we can keep track of numbers.
NOW CONCENTRATE! - REMEMBER - 2000 IS THE YEAR OF THE GRASSHOPPER AND YOU ARE GOING TO TAKE PART! ENJOY - NEXT YEAR IT MIGHT BE EARWIGS.
