National Museums Liverpool Blog - bug house

The job of a National Museums Liverpool press officer is a varied one. With such a diverse family of museums and galleries, there are many opportunities to highlight our exhibitions and events within the press, but not all as exciting as yesterday…well, for me anyway!

Here I am with my one of my favourite little characters from the sessions, a gorgeous Pigmy Hedgehog

As a life long lover of Meerkats (yes, I even liked them before those well-known price comparison adverts hit our screens) I was chuffed to bits to be invited along to a press opportunity ahead of some fantastic Meerkat-tastic events that are taking place at World Museum over the next couple of weekends as part of National Science Week.

These gorgeous little creatures will join other live desert and rainforest creatures such as snakes, reptiles and spiders (I’ll be steering well clear of the creepy crawlies!) for free close encounters sessions this weekend and next. You’ll even get to see some weird and wonderful African and Egyptian hedgehogs! Beware of cuteness overload!

Come along to World Museum for sessions held at 11am, 12:30pm, 2pm and 3pm tomorrow, Saturday 13 and Sunday 14 March, and at the same times on Saturday 20 and Sunday 21 March 2010 for your own close encounter.

The sessions last an hour, and are free when you collect a ticket from the museum’s information desk on the day to secure a place.

For more Meerkat pics, theres a gallery on the Liverpool Echo website.

I know I'm a day early, but 2010 will mean a pretty important anniversary for us here at National Museums Liverpool. It will be the 150th Anniversary of William Brown handing over the keys for what was then the Liverpool museum, which we now all know and love as the World Museum.

To mark this anniversary we’re going to be featuring a year-long series of World Museum-related stories on this blog. There'll be a story a week, with a mix of historical and contemporary pieces. We want to let you know all about the museum’s history but also give you a few behind the scenes peeks at the people, stories and events that make (and have made) this such a special museum.

To give you a taste of how the museum first came about, I can tell you that on 8 March 1853 the museum opened for the first time on Slater Street in Liverpool. It was then called the 'Derby Museum of the Borough of Liverpool' in honour of the Earl of Derby’s bequest of over 20,000 natural history specimens. We still have amazing specimens at the museum, ranging from an Arctic Fox to many beautiful butterflies.

We'd also like you to get involved by sending us your memories of the World Museum from both past and present. If you have a specific date that sticks in your mind, then all the better. You can submit your memories as a comment at the bottom of this post.

So all that remains is for me to wish you a Happy New Year and to invite you to come along and visit our fab, free museum in 2010!

Bug House Demonstrator, Rebekah Beresford, is back again to tell us about her latest project in the Bug House at World Museum Liverpool. This time she has been giving the Hermit Crabs' vivarium a make-over! You can see the photos from each stage of the project on our Bug House Flickr set.

The Hermit Crab vivarium

After the success of the Indian Ground Beetles display earlier this year it was decided that some of our other vivariums could also do with a revamp! The Bug House hasn’t kept any mantids for over a year now and they’re incredibly popular with the visitors - so the next vivarium on the list was their display.

The new vivarium arrived from Exo Terra and was made by leading experts in the world of exotics. We got to work on siliconing in a glass partition, a third of the way along the tank to create a fresh water pool. Hermit crabs require fresh water so that they can mix it with salt water. The crabs then pull up into their shells their own preferred salinity reservoir from which they can breathe through. The fresh water pool in this vivarium will house a variety of aquatic invertebrates such as apple snails and gammarus (shrimp-like amphipods). The pool will also be useful for maintaining the humidity in the tank.

Coming from the Caribbean, these Hermit Crabs require humidity of around 70%. Hermit Crabs are avid climbers so it was important to factor this in to the design. A polystyrene wall made to look like rock work was ideal. It was easy to cut and wedged into place perfectly down one side of the vivarium. With some plants and bark attached the crabs would have plenty to climb and perch on.

Once the silicone had dried we tested it for leaks and luckily there weren't any! The pool was filled with gravel and the waterfall was set in place. The waterfall runs with a small pump set inside it. It’ll make the finished vivarium look quite impressive.

Hermit Crabs are renowned for being boisterous and particularly clumsy, so it was necessary to silicone some bark along the rim of the glass partition. This would prevent substrate from being kicked into the pool and also to allow leverage for the crabs to pull themselves out.

Whilst this was setting I had time to add the substrate to the land area. Hermit crabs dig themselves under ground for protection whilst moulting. Being invertebrates their skeleton is on the outside and moulting their skin to grow is a big deal. In the wild predatory birds could snatch them above ground level so they are forced under ground to do this. Even though hermit crabs are social creatures they are still opportunistic feeders. They would happily eat a moulting crab which would be soft and vulnerable and unable to protect itself, so it was important to factor in plenty of space to avoid this.

The next thing was to rehydrate the coco fibre to mix with the sand. Coco fibre comes from the husk of coconuts and is widely used in vivariums to provide sound air content and moisture in the substrate. The coco fibre was then added to the land area creating a gradient. This could then be mixed together lightly but the crabs would do a good enough job mixing it together themselves.

One of the last requirements for the vivarium was to add the climbing material. Drift wood is perfect for this because it’s so robust. I used smaller pieces along the climbing wall in steps for the hermits to climb over. Before it goes out on display I’ll add some bamboo and extra foliage.

Thanks to Phil from the aquarium, I was able to acquire a rainforest creeper called Devil’s Ivy. It’s commonly seen for sale in garden centres as house plants but its native to Asia. The plant was trained around the drift wood through to the fresh water pool. It’s a climbing plant and clings onto tree bark using its aerial roots. It’s also very hardy so will re-root itself quickly if the hermit crabs dig it up several times.

The Hermit Crab vivarium is now on display in the Bug House so come along and see them in their new home!

Bug House Demonstrator, Rebekah Beresford, tells us about the latest addition to the Bug House...

The weird and wonderful Wandering Violin Mantis

So, may I present to you the Wandering Violin Mantis or Gongylus gonglodes. This awesome looking insect is our newest addition to the Bug House. We have eight of these funky little creatures and they’re one of the most bizarre looking out of all the mantids.

These insects are part of the order Mantodea and are characterized by their slender limbs and stocky upper body. As suggested by the name, this mantis looks somewhat like a violin with leaf like appendages protruding from the legs to aid camouflage and a leaf like head. They’re from Southern India and Sri Lanka and come in a variety of different shades of brown.

The wandering violin mantis is more of a ‘sit and wait’ species rather than a hunter but that’s not to say that they’re picky. These mantids are confident, ravenous feeders and will snatch a variety of flies and moths from the air, if the dare to fly close enough. Most mantids are solitary and have to be kept individually but these are unusually social. Given plenty of space they can be housed together in small groups of 8-10 and pose no threat to each other. 

So, keep your eyes peeled for them in the Bug House! I’ll be putting them out on display in the next few weeks in a mixed exhibit with the hermit crabs and fresh water shrimps. Also keep an eye on the blog for my next posts on how I set up their new vivarium.
