RECORDER'S REPORT FOR ENTOMOLOGY and OTHER INVERTEBRATES 2012 



Chris Raper 



Despite another very poor year for summer weather, it was nice to see some of our favourite 

 species returning, if in lower numbers than in some years. The wasp spicier was found in a couple 

 of locations around Reading and a few Spring specialists did very well this year. In particular I was 

 surprised to see a new species of tachinid (Gonia picea) on Hartslock Nature Reserve - a site that 

 I have been associated for over 20 years. To me, this shows that successive warm, sunny Spring 

 weather has benefitted some of the early emerging species. However, this contrasted with steep 

 declines in some of the "common" mid-summer species, which were nearly absent. 



Many thanks to all the observers who persevered in difficult circumstances!
