Our last visit of the year to this prolific nature reserve that always springs a surprise on us, and this night was no different.
With a warm South-westerly breeze dominating the weather forecast and lows of a comfortable 15 degrees, we once again decided to run traps on the Boxmoor Trusts land.
The hope was to turn up something unusual for the site or intercept a migrant (for which there were plenty about).
We succeeded on both accounts and star of the show had to go to a worn Maiden's Blush looking moth which Ian Bennell found in the long grass, several feet away from one of my traps.
Passing it around to everyone it just didn't look right for this species and the brain thought of other possibilities which were quickly narrowed down to either a worn Maiden's Blush (likely) a Clay Triple-lines (still quite likely) and then the absurd (Jersey Mocha).
The moth was retained and dissected the next day and I was literally on the edge of my seat awaiting the results back from Graeme Smith. When he said that it is a Jersey Mocha, that inkling to retain the moth was all worth it! Graeme had to promptly get a cup of coffee to calm down as neither myself or he could believe it, another new to Herts this year! And hat's off to Ian Bennell for spotting it and not just discarding it as a worn Maiden's Blush.
Other good species included a pair of Psoricoptera gibbosella (Only my 2nd and 3rd examples in 10 years), Hellinsia carphodactyla (Which was new to me) and Depressria badiella (Which was retained and also dissected by Graeme Smith and a great record for Herts, again NEW TO ME!)
What a fantastic night it was and thanks go out to David, Roger and Ian for helping me make the night a success and for being as eagle-eyed as ever.
