I have been inundated with copy for this issue which is brilliant and I have had to put in four extra sides to accommodate it, please keep the copy coming in. It has also been excellent to get copy from some new contributors commenting on some pleasing subjects from Suffolk. One piece I would like to highlight is on page 16. This calls for sightings of Turtle Dove to be submitted via the Suffolk Biological Records Centre’s online recording pages. These online recording pages will allow users to use interactive recording forms to submit wildlife sightings. The system, which is built upon the same technology being applied by the likes of iRecord, is in its final stages of testing and will be formally launched very soon. However, parts of the site, including the Turtle Dove recording form, are fully operational and can be found here www.suffolkbrc.org.uk/turtledove. Please may I draw your attention to the list of bioblitz and recording events that SNS is getting involved in this year, these can be found on page 4. One of these events, the Holywells Park bioblitz, is being organised by the Suffolk Wildlife Trust and their new HLF funded ‘Closer to Nature’ Project. This project, by working with Ipswich teenagers, hopes to encourage the next generation of natural historians and they are also keen to work with Ipswich Museum and use its natural history collections. Finally, on a more sombre note, Darsham Common, adjacent to Darsham Marshes has been donated to SWT in the memory of Peter Lawson, SNS member and respected botanist who passed away last year.

I became aware of them by chance. In October 2014 I found a small green wasp resting on a parsley plant in my garden near Christchurch Park in Ipswich. At the time I thought it was a fly! However, under the microscope I saw it was worth photographing because of its striking colour and the interesting sculptured texture of its surface. I posted the photos on the Facebook Hymenopterists Page where the family was quickly identified as Pteromalidae. A key to the European Pteromalid species indicated that it was a male Halticoptera flavicornis, a parasite of flies. Hannes Baur, an expert on these wasps based at the Natural History Museum at Berne in Switzerland, subsequently confirmed the identification. Pteromalus cf. albipennis Halticoptera flavicornis 6 White Admiral 90 Having become interested in these cf. albipennis. These wasps are tiny insects, I remembered a parasitoids of fruit flies specimen I had collected near the (Tephritidae) developing in flower Martlesham Recreation Ground in heads of Asteraceae, for example July.
