Moth Watch

We will shortly be conducting another Moth Watch here in the Garden and it will be interesting to see how it compares against our last Watch in July.

The results from July were most illuminating. The Great Reveal, always an exciting time, this year  helped us record  a total of 58 species in all.

We were most grateful to Mark Spencer from Bournemouth Natural Science Society for setting up the moth trap and recording and helping us identify our  visitors.

Below some images from the survey:-

What a difference a few days make

Two reports here from our lepidopterology and odonatology expert, Keith Powrie demonstrating the difference only a few days can make in the Garden. Read on for Weeks 15 and 16 below!

Week 15

Another poor count week. It seems July isn’t going to be much better than June! Just 15 butterflies were counted.

The average for this week at Knoll is 32.

The most common, with counts of 4, were Green-veined Whites and Ringlets. The only ondonata present were Azure Damselflies, with no dragonflies being seen at all!

Week 16

What a difference a few days makes!

On the 12th, the Week 15 count yielded just 15 butterflies of 7 species.

A few days later, on the 15th, Week 16’s count was 31 butterflies of 11 different species.

Mind you, the presence of some sunshine does help!
Several new species were enticed onto the wing:

Small White – usually as a migrant, brought over on southerly winds from the Continent.
Comma – 1st brood from overwintering adults.
Gatekeeper – single brooded in mid summer.
Holly Blue – first appearance of 2nd brood.

The cool conditions between the short bouts of warm sunshine, have curtailed the emergence of dragonflies. A few Azure Damselflies were pairing up and egg-laying, but only one Large Red Damselfly was seen.

The only dragonfly seen was a male Brown Hawker – searching for a mate. Let’s hope he finds one soon, before the next lot of bad weather arrives!

Some distance from any water feature, was the discovery of an adult Banded Demoiselle.

Every creature counts – Annual Garden Wildlife Survey

Annual Garden Wildlife Survey Tuesday 6th August
This year’s Annual Garden Wildlife Survey takes place on Tuesday 6 August from 10am – 3pm normal garden admission costs apply. There’s no need to book, and £5 of each garden admission ticket will be donated to the Knoll Gardens Foundation.

If you’d like to know more about the wide variety of creatures that may be living in your garden the Knoll Gardens Annual Garden Wildlife Survey is a great place to start. Led by experts from the Dorset Wildlife Trust, this special day takes place every year to create a vital snapshot of the wildlife activity in this east Dorset garden. The survey provides an important year-on-year record, and offers the opportunity for everyone with an interest in wildlife to get involved – beginners and experts alike.

Learning more about the relationship between Knoll’s flora and fauna is a key part of the work of the Knoll Gardens Foundation, the garden-based charity set up to understand the ecology of the garden and encourage others to adopt techniques that benefit the gardener and garden wildlife. In addition to the Annual Garden Wildlife Survey the Foundation also organises regular surveys of its populations of birds, butterflies, moths, bees, dragonflies, reptiles, mammals and bats.

“2019 has already seen some unusual sightings across the country with hot weather in Europe bringing an influx of Painted Lady butterflies in June and  unusual birds including the European Bee Eater and Purple herons”, said Knoll’s owner Neil Lucas.

“Whilst we are not expecting to spot anything as substantial as a heron, we will be on the lookout for rare Scarce Chaser dragonflies as we have had a female guarding her territory by a pond for nearly two months and would love to see her find a mate”.

“Last year the survey also found an amazing variety of other insects including long-winged Conehead crickets, Batman hoverflies, Beewolf wasps and Fork-tailed Flower Bees. We hope they are all still thriving alongside the garden’s many other insects, birds, mammals and reptiles. I’d encourage everyone to come along and find out more about the wide range of creatures that may be living in their own gardens.”

This year’s Annual Garden Wildlife Survey takes place on Tuesday 6 August from 10am – 3pm normal garden admission costs apply.  There’s no need to book, and £5 of each garden admission ticket will be donated to the Knoll Gardens Foundation.

Butterfly Watch

Below, a recent report from Keith Powrie of weekly butterfly monitoring carried out on the 6th July.
It will be interesting to see how the improved weather of late might affect forthcoming sightings.

A chance to see for yourself:- Guided Butterfly Walk – 19th July 2019 – £5.50
In line with the nation’s Big Butterfly Count, dedicated lepidopterist Keith Powrie leads a walk from 11am to 12.30pm around the gardens to help you identify the many butterflies to be found there. Keith has been recording butterfly sightings at Knoll for many years and brings an infectious enthusiasm to any guided walk.
Book online

On the 6th June, a female Scarce Chaser Dragonfly was seen in contest with another female, for a territory on the left of the path leading to Mill Pond.

One month later and the victor is still holding the same territory – unless they’re taking turns! It would be great if she could find a mate and the Gardens could have their own breeding pair. Unfortunately we’ve never seen a male in the Gardens, so we hope she has better luck than us.

June was a complete washout as far as weather is concerned and the conditions required before a walk can be carried out, were seldom met.
Consequently, emergence of summer butterfly species has been delayed and curtailed.

The average count for Week 14 is 21 – only 14 were discovered this year.
4 Green-veined Whites; 4 Meadow Browns; 4 Large Skippers; 1 freshly hatched, second brood Speckled Wood and, a glimmer of hope for the rest of the summer,a Painted Lady – a migrant carried over on the southerly winds of recent.

June Sightings

Our thanks to Keith Powrie for this latest report and pictures from the Garden.

Week 8 produced just a single Holly Blue.  Since then the weather has been abysmal and quite unsuitable for carrying out any butterfly counts, consequently Week 9 was missed completely.

On Thursday, we managed to fit in a walk for Week 10, before the promised deluge. It was pleasant in the sun, but the north-westerly wind made its presence felt when the clouds appeared.

Once again, the butterflies were thin on the ground, with a female Common Blue being the only one of real interest.

Large Red and Azure Damselflies were present at all the ponds, with a few also scattered around the Gardens.

However, the sight of 2 female Scarce Chasers together, around the flower beds leading to the Mill Pond, more than made up for the lack of other dragonflies.

Friday 21st June – Two good reasons to visit

It is a National Garden Scheme (NGS) Open Garden day at Knoll on 21st June and the Dorset Wildlife Team will also be here with their ‘Get Dorset Buzzing’ Roadshow.

The NGS is the most significant charitable funder of nursing charities in the country.
Your visit today will help its work. Normal admission charges will be donated to NGS.
In the Garden today is the Dorset Wildlife Trust ‘Get Dorset Buzzing’ Roadshow.
This year Dorset Wildlife Trust aims to get 1,000 gardens in Dorset doing at least one thing to help pollinators, whether it’s planting up some pollinator-friendly plants, building a bee hotel, or simply leaving a wild area.

We are delighted to support this important campaign and welcome the DWT Roadshow to Knoll. With fun activities, hints and tips it is a great way to find out how to ‘Get Dorset Buzzing’ in your garden. (Free garden admission for members of DWT and anyone joining DWT on the day. Please show your membership card on arrival)

Get Dorset Buzzing is a Dorset Wildlife Trust Initiative. Find out more from the Get Dorset Buzzing website Link below:

Spectacular Spring Butterfly Count

The environment in the garden is clearly working for our wildlife as this recent report and picture from Keith Powrie,  (our friendly expert in lepidopterology and odonatology) shows :-

“Last week’s count was pretty spectacular.
21 butterflies seen of 5 species:10 Brimstone; 2 Green-veined White; 7 Orange Tip and 1 each Peacock & Speckled Wood

This week with a temp of 25°C (Compared to 13 last week)
only 13 butterflies seen:4 Brimstone; 7 Orange Tip and 2 Speckled Wood.

However, the first damselflies of the season were spotted.
2 Large Red Damselflies, 1 at the Upper Falls Pond and another at the north end of the gardens.

Also a pair of Buzzards were observed chasing a Red Kite out of their territory behind the tunnels.

And a Grass Snake was seen swimming across Upper Falls Pond, eventually taking refuge under the overhanging Gunnera leaves.

Quite a jolly day out!”
