Field Trip - Croxley Common Moor - 12/07/19

I was invited to help out at a public event at Croxley Common Moor.

It was a privilege to run some traps on this unique habitat (particularly for Hertfordshire).

I was joined by David and Roger and Graham whom is the secretary for the reserve.

We setup 7 traps in the centre of the reserve and waited for the general public to arrive.

The moths were quite slow to respond to the lights and there weren't many big moths at all to show the masses, we did however did pot a few nicely coloured moths, Agapeta zoegana (or Zoe) was a hit with many of the guests, owing to its bright yellow colours. Kent Black Arches was nice and intricately marked and a good one to show around. It was nice to share my enthusiasm with others.

Once everyone had left at around 11:30pm, it was down to the business of recording the moths and seeing what specialities were around. Although numbers and species were low due to the unfavourable mothing conditions (cool, clear and a bit windy) we did manage a few goodies! The site is full of Broom, Gorse and Dyer's Greenweed... hence the special species represented moths that feed from these foodplants

Agonopterix assimilella, Trifurcula immundella and Leucoptera spartifoliella were all new moths for my records and all associated with the above foodplants.

We also managed another two great species both Caryocolum fraternella and Sophronia semicostella are not common in the County, and another two new ones for me.

Once again, thanks to Graham for allowing us access to this site.

Here is the total list.
