I run the risk here of irritating brother Matthew: he probably believes that to quantify HIM is sacrilege. Nevertheless, I'm so happy about the last two wonderful seasons here in Upper Thames, I just have to report it.
1] 2009 was twice as good as any as the previous 6 seasons, but 2010 was even better with 75% more sightings than in 2009. I've no idea why; has anybody?
2] HIM was seen in 46 localities, of which 12 were new habitats, by 45 recorders
3] The best territory was in a very small wood, aptly named Little Wood. Around one huge Ash and several Oaks at the highest point, sightings were made on 15 days between June 28th and August 7th: a 40 day period.
4] The first sightings were on June 28th, and the last on August 8th.
