 I have a new spider. This, which you can just see on the camera, is probably a baby Marpisa Muscoza jumping spider. The reason why I have this is that I actually have a adult female jumping spider who appears to have mysteriously laid some eggs and this is one of her offspring. I say appears to and probably because she hasn't really seen a male for a while and as a result I'm not entirely sure where the eggs came from. Four of these spiders showed up in her enclosure and there are baby spiders and I can't think of any plausible explanation for them other than them being hers. So there you go. Marpisa Muscoza are a species of European jumping spider. The mother or at least probable mother Ishten is currently asleep in her enclosure after eating an extremely large fly so what you're seeing now is B-roll footage from previous attempts to make a video on her. She's about a centimeter and a half long. She eats a fly roughly twice a week. She's local to where I live in Switzerland coming from just down the road. I put out the call to people at work saying I was looking for a spider and someone has a house full. So there you are. Jumping spiders are great little pets. I keep Ishten the female in an enclosure on my desk where watching her kill things provide a great amount of solace during long boring meetings. Anyway back to the spiderling. This one has currently been living in this little pot for a little while and I want to upgrade it to a slightly better enclosure. In particular it's probably gonna want to molt soon so I'm going to want to get the humidity up. I did originally have four of these. I presumably Ishten laid four eggs. One escaped. One showed up very small and lived about a week and died and the other big one just turned up dead the other day. This is kind of par for the course with baby spiders. They're not very well made but I want to be a little more careful with this one as it is the last so we shall see. So all I'm really going to do is to put together a very simple little enclosure out of these pots, a piece of grass and some rough fabric that I happen to have lying around. So now I'm waiting for the hot glue gun to warm up so I will do a jump cut. So the way this is going to work is I'm going to end up with two of these cups arranged like this with these lids between them glued together. The bottom one will contain a little bit of water to keep the humidity up and also a window to the outside to let air in and the top one will contain the spider. Spiders do breathe. They actually have reasonably complex breathing apparatus. Most atheropods don't but spiders have simple but workable lungs. They breathe through up to about four nostrils on the underside of their abdomen which is effectively their stomach which is why spiders are very nervous of water because all their nostrils are on the underside of their body but we do want some ventilation so I'm just cutting out a window from the side of this pot like so and the way this is going to work is the two lids will be glued with hot glue like this with a window through them both and a piece of this fabric glued in between to let air and humidity through but not spiders. Okay so let's cut a crude hole in the middle. Doesn't need to be particularly big. We do the same again. That's about a centimeter square. It's nice if these were actually square but never mind. Perfect! They're even about the same shape which is slightly unusual. Okay so let's cut a smaller piece of this fabric. This is a piece of I think it's paper cloth which came from a rice bag but it should do fine for this. It's relatively porous. Okay so blob down some hot glue down the fabric a bit more glue and then the other side like so. All right so we have one pot with a window this is going to be the water side and this is the actual habitat so we take the grass and we cut this a little and this is going to be... this is just going to add a bit of interest to the environment for the spider. These Mopissa muscoza they don't really have much in the way of a colloquial name but I've seen them referred to as fence post jumpers. Actually seem to have a interesting behavior in that if you give them stuff to do when they're a baby they actually grow bigger brains so they become more intelligent as an adult but I just want a little bit of space for the spider to crawl around and somewhere to make the little hide a sort of nest except they won't actually be formally nesting in it and where it will sleep. This one in this pot you can actually see possibly not on camera I'll see what I can do with zoom and enhancement but there's a little silk hammock up there which is where the spider lives. The spider is currently wandering around in some degree of agitation because I'm moving its enclosure around. We will by the way not know whether it's male or a female until much later on in its life. It will have to molt several times and grow. That's that glue has hardened. I just want to try and get a bit of stray glue out. Hot glue is great for this stuff because it's easy to work with and is non-toxic. There we go that's not really as robust as I want it to be. I wonder if the nozzle is big enough to get a blob down there. Yes it should be. Okay so what will probably happen is the spider these are arboreal spiders they live in trees and bushes so it will climb to the top of the enclosure which will be this way up and it will probably settle down somewhere in the fork of the grass and build its hide there which is why I put a forked piece of grass in. So now that is done I am going to wait for the hot glue to set and put a little bit of water in here and we'll come back and actually see what the spider thinks of its new home. Okay that is now cool so we should be ready to go. So we have pot full of water a little bit of water and we clip our stuck together lid on there and now we want to transfer the spider who is watching me with great interest from this container to this container. Jumping spiders are active hunters they don't build webs they will stalk their prey and they use a decent brain and two very good eyes to actually do the stalking. They also jump hence the name so I do need to be a bit careful that it doesn't try to get away like that. It has jumped off the lid onto my workbench but I have put that the new enclosure over the top of it so it can't get away and I'll just wait a bit to see whether it decides to climb up or not. Okay I let it be for a while and it has indeed climbed up to the top of the enclosure and is investigating so now I just need to put this on here and just clip it down. In fact I believe that is not showing up on the camera but it is wandering around the enclosure it should just be reaching the top on this side so you may show up. Yeah you can see a little dot there which I will attempt to zoom in on in editing but yeah that's it so I will go and place this somewhere where it won't get knocked over and leave it till tomorrow and then try and feed it. It eats fruit flies. I hope you enjoyed this video. Please let me know what you think in the comments.
