Ditton Park Wood - Field Trip - 09th August

I made a trip back to Ditton Park Wood armed with 4 traps this time.

Go all out of go home, and indeed it was well worth the extended effort with an extra trap in tow and staying until 2am yielded 182 species in total, a very good August count.

 

There was a good selection of macro and micro moths, but the larger moths were once again a poor showing in comparison with the clouds of micros around each trap.

 

Trying to pick out the quality is never easy, with hundreds of Eudonia mercurella flitting about frantically.

 

Best macros included Ruddy Carpet, two Small Wainscots, a smart Oak Nycteoline and a single Clay Triple-lines spotted amongst a few Maiden's Blush.

 

On the migrant front there were at least 60 Small Mottled Willows across all of the traps, backed up by two Acrobasis tumidana and a smattering of the other regular migrants.

 

I was very pleased with the all white form of Argyresthia bonnetella and an equally nicely marked Acleris laterana, sadly escaping from the pot whilst trying to photograph it. A pot shot would have to do! 

 

Despite the recent workings in the wood, with lots of logging evident the moths were still in profusion.

Quiet on the new ones

Not much to write home about on the 7th.

A single Straw Underwing saved the day as the sole new species for the night.

A very clean-lined Agriphila tristella nearly got mistaken for a latistria (A moth I was lucky to take only once when I holidayed in Dorset last year).

Two Lychnis were noteworthy, previously I have only ever recorded singles to my trap.

That was about it really.  

Things got a little more varied and interesting as we headed into the weekend.

Mostly Nutmegs

The garden trap is currently dominated by Nutmegs. I find it really odd these population explosions.

Trapping a mile away at the nearby fen I recorded only 1 recently, over 4 traps! On Thursday night I got to 108 by the morning.

I took a picture of just one of the outside trays, covered in Nutmegs!

 

I have had this explosion experience before way back on the 25th of May 2011 on my parents old farm, post below.

 

https://www.blogger.com/blog/post/edit/2967709613991032655/3653422830189891010

 

That night I recorded no less than 220 Nutmegs over 3 traps!  

 

Some returning macros including Oak Hook-tip and Treble-bar.

 

Best moth of the night was a tiny Endothenia oblongana, confirmed by checking the upper side of the hindwing. 

A scarce moth here in Cambs, but probably less scarce than we think, due to people discounting them as marginea or gentianaeana.

The very pale white transversal band towards the tornal area can be a general indicator of this species. 

 

It is moth no.958 for the garden. 

Another heat wave coming up, heatwave number 11786.

A new species for Cambridgeshire!

I did my check of the lure bucket traps around the garden on Tuesday evening, it is getting a little late for any interest now with just Raspberry and Dusky most likely in this late period so I am not expecting much now.

There was nothing in any of them, until I got to the loranthi lure, intended for Synanthedon loranthi (A non-British species) I found a tiny (unfortunately) dead moth in the bottom.

Under a hand lens I could see it was a Tortrix species and looked close to a Cydia conicolana, but revisiting it later on in the day, it certainly appears to be Pammene juniperana, especially with the light yellow tiger stripes in-between the vertical metallic bands.

The moth appears to be new for Cambridgeshire and one I have certainly not seen before so very worth trying these different lures. A bit gutted it had already kicked the bucket.

In a week, all of the lures will go away in the freezer for next years use.

Stenoptilia zophodactylus was another surprise, keyed out to this species by the all white thoracic saddle and all white legs.

This species appears to have not been seen in the county for over 120 years! Most probably over-looked.

Apodia martinii was the third new species added to the site list

Three garden firsts was exceptional for August.

These were backed up by a year first Rosy Rustic which went missing in 2025.

Speaking of going missing, it seems like it will now be a two year absence for the Lesser Swallow Prominent in my garden and to any of my traps in the field. What has happened to this species locally over the last few years is unexplainable currently. A once common moth for me.

I also took a few pics of some more common moths. A Nutmeg.. one of around 500 this past week that have graced my trap.

Still warm ;l

August brings about new grass moths

Another fairly good catch to bring in August and last Sunday was warm and humid overnight.

The lack of rainfall is starting to become rather worrying, as we have only had two 15-20 minute downpours in 8 weeks now. The first one barely filled the two 80 litre water butts, and the second filled the front one, and made it half way on the back on (only coming off a small shed rood mind).

Best moth of the night went to a smashing Bordered Pug, my second for the garden and last seen 4 years ago! 

A second yearly record of Aroga velocella was also nice, a moth I see far more commonly out on the dry sandy heaths, mind you.. the garden is currently turning into one!

A few migrants also made it through, most notable was the 3rd yearly record of Dark Sword-grass.

Trying to catch up before more warm humid nights approach, this is never-ending!

A mini resurgence

Numbers crept up on Friday night here in my garden, on what was to be the last July night of 2026 and what a hot month it had been, carrying on fluidly from the warmer than average June.

Sadly, we still are in desperate need of significant rainfall. 

We've only had a few hours of rain in the past 6 weeks now, and even then it literally ran off and evaporated in the hot July sun that followed. 

I counted around 60 species, which is pretty good for late July here, as we come away from the peak mothing season.

Ancylosis oblitella has had a really successful year, with over 15 records this year alone. In previous years it has only been recorded in 1's and 2's. 

During the days and particularly in the early evening I have had visits from Hummingbird Hawk-moths, I managed an ok photograph of one of them, they a super quick!

There were two welcome new species for the year, a cracker of a Red Underwing and a Flounced Rustic.

The third Striped Hawk-moth of the year was great also, sitting proudly next to the Red Underwing! It was a new species for the garden only this year.

The best of the rest were too boldy marked species, Scrobipalpa atriplicella and a White-line Dart, both showing stronger markings than normal specimens I encounter.

Worth keeping an eye out for Scrobipalpa atriplicella, they can be hard to pick out amongst ocellatella, slightly larger and much more strongly marked and lacking the pale ovals around the ocelli. 

Still warm out there folks...

A smattering of new moths, a little samey towards the end of July

It's gone a little samey in my garden recently, with only 1 new species on the 29th of July.

Still between 35 and 50 species on the nights I've been running my trap, mainly dominated by Small Mottled Willow and Nutmeg, the latter last night broke through the 100 examples barrier, with 76 alone the night before. 

Small Mottled Willow is the talk of the town recently with a lot of people recording record amounts, with reports of over 1000 last night in Dorset.

Here I've been getting around 20 to 30 peak.  

 

Below are the highlights from last Wednesday.

 

Cacoecimorpha pronubana - The first female I have seen here this year. The males have been prolific from late Spring, and just love the pheromone lure, in fact if I get the bag out of the shed, they'll just appear from nowhere within a few minutes, it must be so impregnated! 

 

Dark Spectacle - Only my 2nd record this year, never a common moth compared to its sister species the Spectacle. 

Nemapogon koenigi - New for year and an annual visitor here, sometimes to the Yellow-legged Clearwing Lure (VES).

The drought continues here in the East.

Chippenham Fen - Field Trip - 28th July

A made an overdue trip to Chippenham Fen last Tuesday night, I'm not sure where the 5 weeks went between this visit and the last, but the warm weather has made time fly very quickly indeed.

Another warm day, well warm week infact!

I arrived just as it was getting dark and it was a quick setup and lights on at around 9.20pm, the nights are certainly drawing in fast now, even when its a clear sky.

There were variable amounts of cloud, clearwing by packing up time at 2am. A big bright moon was also present, but quite low in the sky so no issue whatsoever. 

212 species were recorded over the 4 lights that were ran. The poorest trap was the 30w led, it was so bad that I canned it at midnight. This is really odd as this trap did very well at two other sites recently.

Both the 125w MV in the field edge and the 250w by the barn faired very well indeed, and it was hard keeping up with the species coming in, although numbers weren't as large as I had hoped and the summer peak has definitely subsided now. 

Amongst all of the moving moths were two stars, a first for me Great Brocade, and another new moth in the shape of a small geometer, a Rest Harrow.

The latter I presume is a wanderer from coastal populations, but the former could have well been a genuine migrant, who knows!

 

Other gems included (not a Gem sadly) 3x Vestal, Apodia martinii (name change alert), lots of Dingy Shell's, 2x Elachista bedellella, Golden-rod Pug, Lyonetia prunifoliella & Square-spotted Clay.

 

A right result for the end of July.
