Fox Moth have 5 instars i think and your latest pictures from the 4th the last instar they tend to be chestnut coloured with longer hair and less yellow rings. They tend to hibernate in September and be fully grown in August so on time.

The white wing fringe is also more visible in DGFs as shown in the above pictures.

Marsh Fritillaries will eat other plants, Other Scabious Species, Plantain, HoneySuckle, Knapweed, Just as Glanvilles will eat Speedwells in the wild. Just because books say only Devils Bit, doesnt mean they dont use other foodplants in the wild. Remember Brown Argus was said to only eat Rock-Rose n...

Ive got Fox Moth larvae through the winter with one method, and the metod for a few butterfly larvae should work too. Fox moth larvae tend to get damp then get mouldy which is why they dont get through.

Not sure how self sustaining the hutchinsons bank Glannies are :? There were 23 Glanville larval webs last year, each being closely monitored and marked onsite, 22 of which were found again in January when the larvae woke up from where the hibernation webs were located, web 2 was 6 inches up a hawt...

I see Marsh Fritillary are now on the species list at Hutchinsons bank. Yet another unofficial release I assume. That place is turning into some kind of butterfly zoo. Cheers, Neil. It seems thanks to the Marsh Dumper last year, they bred on at least 2 of the sites and produced some butterflies thi...

I see Marsh Fritillary are now on the species list at Hutchinsons bank. It was dumped there last year during lockdown, along with sites like Denbies Hillside and 30+ other sites across the South East, bred in the cutting, and we were not pleased, if they introduced Cotesia bignelli to the site, as ...

We had a Small Copper ab at Hutchinson Bank today.

The Hutchinsons Bank one was seen again today, so its still around, hope to see it tomorrow or the next few days.

The larvae become more visable in June, so you should notice them when they move to the leaves.

I think the Wrecclesham population is behind a strong fence now, people were removed from the site in 2019. I managed to see Glanvilles at several sites last year 4 in Surrey and 1 in Kent, none of these were Wrecclesham or IOW.

Snap, Lovely day at Hutchinsons Bank in the cutting, the first female Glanville Fritillary emerged, the photos clearly show the differences between the sexes.

Again a very fresh male, hopefully they will have another good sunny flight period, numbers of larvae seemed to be higher this year.

Our first male emerged at Hutchinsons Bank today, probably the first UK mainland sighting this year.

The Glanville Fritillary Butterflies have finallly started to emerge at Hutchinsons Bank, the first male seen this afternoon in the Cutting, still had floppy wings.

Great hopefully the first of many.

Jason Birder, Why do you say that, in the middle of an influx of migrants, SilverYs, Painted Ladies were all seen that day, and have you ever known Large Tortoiseshell larvae or pupae to be availiable to buy and then actually delivered, Other Large Tortoiseshell sightings have been at High Elms, and...

Large Tortoiseshell seen at Hutchinsons Bank 12th May, missed by the Surrey Butterfly walkers too.

Like all butterflies that over winter as a pupa, the forming up and hatching each year will vary by upto 6 weeks, last year we had 30 degrees in February, this year we had to wait to 30th March for mid-20s temps. in 2020 Dukes and Glanvilles were well out by late-April, the Glanville larvae have onl...

The works at Hutchinsons Bank have now finished, here are a few pictures of the lovely new Bigger Scrape and banks, made as part of the Brilliant Butterflies project. Will be a couple of years before it establishes to its best. Chalkhill, Adonis, Small Blues will use them. DSC00082s.JPG DSC00093s.JP...
