Hymenoptera. The sawflies were well worked, mainly by Andrew Halstead, with 

 52 species already recorded. On 18.ix larvae of Caliroa cerasi (L.) were found on 

 Pyracantha planted by the Society's building; on 20.xi.92 larvae had been found on 

 the more regular foodplant cherry. The alder wood wasp, Xiphydria camelus (L.) 

 was found on 23. v, near alders by the lakes, and Hartigia xanthostoma (Evers.), which 

 mines meadowsweet stems as a larva, on 5.vi. 



Little attention was given to the Aculeata in 1993, with only 25 species so far 

 recorded, but queens of Dolichovespula media (Retz.) were noted between MungelPs 

 Pond and the hedge south of Black Swan Lake on 8.v (when one was caught by Roger 

 Leeke) and again by me on 23. v. Most other species were determined by John Felton; 

 these included three "notable" species: Priocnemis hyalinata (F.) (Pompilidae) and 

 Lestiphorus bicinctus (Rossi) (Sphecidae) were found on Mortimer's Meadow on 31.vii, 

 Lasioglossum malachura (Kirby) (Halictidae) near MungelPs Pond on 13.ix. 



Seven species of gall wasp (two on rose, five on oak) were recorded on 20. ix by 

 Ron Boyce and Andrew Halstead. 



Neuroptera. Nine species were recorded, all determined by Colin Plant. Micromus 

 variegatus (L.), a local grassland and scrub species has been recorded on both September 

 field meetings and in July. Sisyra fuscata (F.) was found near Middle Marsh on 18. ix. 



Homoptera. A nymph of Ledra aurita (L.) was found by the river on 20. ix by Roger 

 Hawkins. Cercopis vulnerata 111. was frequent in the park on 15. v. 



Heteroptera. There are records of 31 species, mostly recorded by Roger Hawkins 

 on 20. ix. Seven species of shield bug have been found including Eysarcoris fabricii 

 (Kirkaldy) near White Swan Lake on 23. v and Aelia acuminata (L.) is frequent in 

 the less disturbed areas of grassland. Coreus marginatus (L.) is often frequent on 

 coarse herbage from July to September. 



Odonata. There is a list of 22 species found in the park in the 1985 booklet. Eight 

 species were recorded on the field meetings; the weather was wet on the day of the 

 dragonfly workshop but observation of settled specimens nevertheless took place. 

 Calopteryx splendens (Harris) was conspicuous by the river on 15. v. Aeshna mixta 

 Lat. was frequent by the lakes during the September meetings. 



Orthoptera. Five species have been recorded, including Tetrix subulata (L.) by 

 Mungell's Pond on 20. ix and Pholidoptera griseoaptera (De Geer) elsewhere on the 

 same day. 



Coleoptera. There are still relatively few beetle records, although some species of 

 interest occurred. Anthocomus rufus (Herbst) (Melyridae) was found by Mungell's 

 Pond on the September meetings. The cardinal beetle Pyrochroa serraticornis (Scop.) 

 was frequent on the riverbank on the May meeting. A Platycis species (Lycidae) was 

 noted on low foliage in the hedge south of Black Swan Lake on 17. vi, the date suggests 

 the little known P. cosnardi but this will require confirmation. Several species of 

 Cerambycidae were noted, including Phytoecia cylindrica (L.), which develops in 

 umbel stems, found on cow parsley flowers near the river on 15. v and other parts 

 of the park later in May, and Leptura livida F. was generally frequent at umbels in 

 June. Andrew Halstead observed exit holes of Agrilus pannonicus P. & M. 

 (Buprestidae) in a moribund oak on Mortimer's Meadow on 13.vi and he also 

 recorded the weevil Notaris scirpi F. by White Swan Lake and Mungell's Pond in 

 June and August. 



Araneae. Martin Askins recorded adults of 20 species and less determinate 

 immatures of several others on 20.ix.92. A further 10 species were added in 1993 

 but knowledge of the spiders is still at a very early stage. 



Habitats in the park. The accompanying map (Fig. 1) indicates the distribution 

 of the principal habitat types (the areas described below are indicated by numbers 

 on the map). The park is dominated today by a series of lakes which are
