Diamondback Moth
Just as a matter of interest despite the huge recent invasion of this moth I
have not caught one this year so far.
this must be just as interesting record
as catching as catching a trapfull

Night of 18th June: Rusty-dot Pearl (2) & Diamond-back Moth (11).

Night of 15th 5 Diamond back 1 Silver Y
Night of 18th 11 Diamond back 1 Pearly Underwing Still good numbers of Diamond Backs on the marsh.

On the last night of the Moth Night last weekend the highlight was a Cydia inquinatana.

136 Diamond-back Moth (Plutella xylostella) & 1 Silver Y (Autographa gamma)in the trap this morning

Night of 15th June . 2 Rusty-dot Pearl , 2 Silver Y , ( White-point ) to garden MV.

8 Silver Y in the garden trap this morning at Great Bridgeford nr Stafford.

Four-spotted (Tyta luctuosa) in the trap this morning

Looking at Diamond-back numbers in this arrival - I have trapped with an average of 7 traps per night for the last 9 nights and feel that numbers when I first arrived in the Hebrides were still increasing. My nightly counts in traps are as shown below (and excluding huge numbers seen by day at every footfall on 9th & 10th!):

6th June = 54
7th June = 11 (maybe habitat less suitable in scrub woodland?)
8th June = 5 (cold night)
9th June = 815
10th June = 465
11th June = 290
12th June = 93
13th June = 74
14th June = 56

Since 10th June there has been a noticeable reduction in numbers seen by day and moths have looked increasingly worn. The only other migrant moth seen was 1 Silver Y on 11/6, though others have reported Painted Ladies here. The peak up here was definitely later than further south in England. Our peak was when you were reporting declines. Trapping was in N Skye on 6/6 and all other nights on Harris & Lewis.

Numbers trapped on 7th & 8th were maybe not representative of the true numbers across the island, but I feel for all other nights they were.

Night of 14 June: Silver Y x 1, Diamond-back Moth x 3
