The weather was glorious for our annual Big Nature Day on Saturday 13 July. Over 4,000 visitors joined us to explore the best of British wildlife in and around the Museum, and soaking up the best of the British heatwave too.

Examining insects and pond life at the outdoor displays in the sunny Wildlife Garden - among the most popular activites at this year's Big Nature Day. Select all images to enlarge them.

Lucy Robinson, the Museum's citizen science manager and worm charming aficionado, reports back with the day's highlights:

'The marquees and Wildlife Garden were packed with over 30 stands showcasing wildlife as diverse as dragonflies, ferns, snakes and insect-eating plants. The Spotty Dotty puppet show attracted lots of the younger visitors with ladybirds and insect friends.

'Our worm-charming competition on the front lawn featured some fierce rivalry, but sadly no worms (who were sheltering deep underground from this hot weather!). Neither fork-twanging, stamping or even music could bring the worms to the surface. However, people could see and hold live worms at the Earthworm Society of Britain's stand in the marquee, so they didn't go away too disappointed.

Worm charming competitions on the front lawn in full sway - participants could twang forks, stamp and make music.

'Some unusual and intriguing things the visiting nature groups brought included carnivorous plants from the South London Botanical Institute, a large metal hedgehog sculpture from the People's Trust for Endangered Species, and some live reptiles courtesy of the Amphibian and Reptile Conservation trust.

The People's Trust for Endangered Species stand showed off a fabulous hedgehog sculpture and invited hedgehog mask-making.

'One of the challenges of organising the event was how to keep the reptiles cool on such a hot day – we had to freeze lots of ice packs and wrap them in fabric in their tanks to give the reptiles a cold area where they could cool off when not entertaining our visitors.

'Making pipe cleaner dragonflies with our dragonfly curator Ben was also really popular (they made over 400 dragonflies before they ran out of materials!). And the spider safari through the Wildlife Garden led by expert Tom Thomas from the British Naturalists Association, along with some fabulous face and body painting.attracted many fans.

Fantastic and original face painting was a hit with families as was zooming in on invertebrates.

'Visitors told us the best parts of the day were seeing the wildlife specimens and meeting all the different nature societies. Kids raved about being able to look through the microcopes, touch the snakes and make lots of things.'

Thanks Lucy. We were also told by our Wildlife Garden team that over 60 insect hotels were made by enthusiastic young visitors, using recycled plastic bottles which they filled with reeds from the Wildlife Garden pond.

Other kids' favourites included the Amateur Enomologists' Society's New Guinea spiny stick insect, the chance to become the Museum's latest specimens on display (right), and dissecting owl pellets (below) with the London Natural History Society.

And the Species Recovery Trust shone the spotlight on some of the UK's rarest species... starved wood sedge, pictured below.

Roll on the next Big Nature Day in 2014.

On the day hundreds of visitors, including many excited children and myself, joined in the Big Nature Count, a bioblitz of the Museum's Wildlife Garden. Researchers and volunteers were out and about with traps, nets and  cameras, conducting samples of wildlife in the 24-hour nature census. A  big malaise trap tent had been set up for flying insects, light traps  for moths and pitfall traps - little jars in the ground - to attract   ground beetles and slugs.

We were celebrating the International Day for Biological Diversity on 22 May. It was sure to be a busy event. With over 300 plant species in the garden there is a lot to attract a wide variety of insects.

The meeting point was the Base Camp tent outside on the Darwin Centre Courtyard, where groups could follow Big Nature Count guided tours with our Museum scientists. But many people simply made their own trails through the Wildlife Garden.

Inside the Base Camp tent, scientists sorted through the samples collected. There were lots of things to see, like a huge stag beetle that I even let run across my hand.

Out in the Wildlife Garden on our discovery trails, we stopped at various tables dotted around the meadows and ponds. Here, helpful experts suggested places to search. On the tables were displays of creatures and samples already collected. My favourite place was the pondlife table. I got rather attached to a shy toad.

Heading into the Darwin Centre atrium after our garden adventures, we had some of our photos printed and added to the Photo wall (below left). After that, it was off to the Specimen Roadshow (below right) to marvel at Ed Buller's flies and wasps, Sandy Knapp's vegetable extravaganza and some 'mucky' soil identification tests.

Because of the gusty weather, there weren't many moths collected in the traps set the night before. And the

recent dry spell meant the worms decided to stay underground. Emma Sherlock who led the worm charming sessions said:

'There were lots of people, but not many worms sadly. Strangely the winning worm charming technique was the stamping while playing the tamborine... hmmm!'

Our entomologists, however, were excited to discover an unusual fly in the day's bioblitz. The little drab wood soldier fly, hasn't been seen before in the Wildlife Garden. Read the news story about the unusual fly found in the Museum's garden bioblitz.

All in all, hundreds of plant and animal species were found in the Big Nature Count. Most of the creatures collected were set free after they had been recorded, but a few individual specimens will be kept in the Museum's collection because they are important for research. It will take a bit more time to identify everything and interpret the findings so we can understand more about our local wildlife, but we hope to have a final count shortly.

Look out for a video account of the day coming soon.
