Jägers on Tumblr

Memes Jägers would have:

  • Tagging pictures of insects “culinary”.
  • Tagging pictures of babies “culinary”.
  • One Jäger posts a picture of a hat and every comment afterwards is the hat badly photoshopped on a different Jäger with a description of how they stole it from the last one.
  • Tagging pictures with the names of long dead Heterodynes because it reminded a Jäger of something they did.
  • Tagging in the accent.
  • Claiming halfway through an argument that they can’t read.

No wonder great philosophers have been inspired by the bee!

SICKadellidae: Or Rather, A Cicadellid with Parasites

Everything has parasites, probably even you.

When reviewing my pictures of insects I often notice hangers-on that would never have been seen unless I had an real-up-close look. I found this tartessine cicadellid this morning - it is likely Stenocotis depressa, a widespread and variable Australian species - on the way to work. Cicadellids are a type of bug often called leafhoppers. It was under the bark of a Eucalyptus planted in a park; one piece of bark (5cm long) examined and one creature found, or so I thought. I never noticed its ‘riders’ until I later reviewed the pictures on the computer. In the first image you can see the leg on the left has a red blob attached to it. Similarly, in the second and third images there are more or these red blobs mostly attached to appendages underneath the body. Altogether there are eight.

Back to the camera and the result is the fourth image. This time the nature of the blob is clear - it is a tiny little mite (0.2 mm) attached with its mouth parts to the front leg (protibia) if the cicadellid. Many invertebrates carry a similar load - mites of many types are common ectoparasites (external parasites) of insects and other arthropods like spiders and harvestmen. In this case I’m not sure of the identity of the mite - if you know it, please tell!

My best guess is that it is likely to be the larva of one of the velvet mites or their relatives (Trombidioidea). These mites have a complex life-cycle with larval stages parasitising arthropod hosts and sucking their haemolymph (bug blood), sometimes quite host-specifically, and then growing up to become voracious, and stunning, free-living predators of small arthropods. Nice, but that’s a tiny little insight into life, right? Now go find out what is parasitising you.

One of the Many Little Things with even Littler Things riding on it!

Konstanz, Constance or whatever you call it, is quite a nice place to visit when you have a day to kill and happen to be around the Swiss-German border. Place the kids into the Sea Life at the border of the lake (a big lake, mind you) and enjoy the stroll through the rather crowded streets of the medieval town center. There’s even a tower to climb in the town’s cathedral, from where the whole lake and the narrow streets of the town can be admired - within limits, as not all balconies on the top are open and the ones which are not are swarming with such a luxurious insect life that taking pictures through the windows is basically useless. That is, unless you like spiderwebs and dead flies in macro view. At the base of the tower there’s a terrace restaurant - obviously - but you won’t get a beer picture from there because as soon as we got our orders, a sudden gush of strong wind threw a heavy umbrella right in the middle of our table, shattering everything in sight. Nobody got hurt - surprisingly - but until we cleaned up ourselves it was time to leave so there, here’s a German beer enjoyed at home instead:  a barleywine from the Bavarian brewery Crew Republic, by its name X2.1 (X for experimental see) and by the taste yummy like malted chocolate just not overly sweet. I would have liked it with some more fruit or more barrel or more hops or more whatever, just more of something, but even so it was a fully enjoyable drink.

If evolution is working blindly how can animals mimic another animals? ex: flies that mimic wasps.

This type of mimicry (where a harmless species mimics a deadly or at least more irritating species) is called Batesian mimicry.

It might be hard to imagine how a species can evolve to mimic another one without some kind of conscious “intent” propelling the changes along. However, in this case it’s important to remember that a species is not selecting itself- it isn’t seeing the dangerous species and deciding to imitate it. The selection is actually driven by the potential predators of the mimic species.

Have a look at this fellow.

Made you jerk back a second, right? Even if you noticed a moment later that the insect in that picture is actually not a yellow jacket. Still, that initial reaction of “ahh, wasp!” is what drove the evolution of this locust borer’s color and shape. The more it looks like a wasp, the more likely you are to leave it alone. Thus, the mimicry is selected for- what might start as a bit of yellow pigment might be guided by predator choice into this sophisticated pattern. Ironic how the predator itself is what decides which pattern is the most effective, isn’t it?

We know that this is truly “blind” selection because not every species mimics a more deadly one- what we might expect if this excellent strategy wasn’t stumbled upon by chance.

Interestingly, Batesian mimicry also has an effect on the species being mimicked- a negative one. It’s easy to imagine why: if a bird eats the locust borer and doesn’t get stung, it’s more likely to then go after the similar-looking wasp and expect no repercussions. This forces the mimicked species to have to constantly (though gradually) evolve to change its patterning in an attempt to escape being confused for its mimic- while predators continue to drive the mimic to change its pattern to match the mimicked species. It’s a real evolutionary war of attrition.

Ahh, the ladybug. And yes I write bug not bird. While Coccinella septempunctata is not an actual bug, it certainly is not a bird. Bug is at least in the same class (insects) as our seven-spotted friend here.

Anyway, ladybugs  are my favourite macro photo subject. Why? Well, they are colourful, compact, easy to manipulate and not that hard to find. They are findable from March to late October if the weather is good. And, of course, you don’t need a rare of spectacular subject to make a photo look nice. In other words, ladybugs for the win.

Photography - What do you think each character likes to take pictures of? like selfies, or nature, etc. ;w;

i love photography sm you’ve got me hooked anon

Lance would be just like you expect and would take loads of selfies. He’d also love taking candids of the other paladins or group pictures with them or their families or even friendly aliens they’ve met. I also think that Lance would be partial to photos of rain and rainy days and clouds and stuff.

Keith would totally go for the hipster aesthetic once he understands the appeal of photography. He would like taking pictures of models in chic outfits and he’s the guy who posts pictures of what he got at starbucks to instagram. He would also like taking pictures of domestic animals.

Pidge doesn’t really have an aesthetic–they take pictures of whatever strikes their fancy, and their social media is a hodgepodge of their interests. That being said, they do have a knack for good camera angles. They are really fond of pictures of insects and the Organized Notebooks/Schoolwork Aesthetic.

Hunk is the kind of guy who takes artsy pictures of abstract art he’s created out of old machine parts and scrap metal. He also likes taking impromptu pictures of people when they’re in the midst of eating, catching them surprised and most often smiling. He has a talent for taking beautiful pictures of sunsets.

Shiro would take pictures of the world around him rather than focus on people or projects or little things. He photographs busy streets and dense forests, sunsets and sunrises and vast oceans. He will treak into the wilderness just to get pictures, no doubt about it.

Allura doesn’t take a lot of pictures, instead preferring to watch her paladins find the perfect shots for their own photography. When she does, however, it’s usually of mundane things that hold a lot of personal significance to her: images of the paladins in the midst of bonding, laughing and smiling, pictures of the planets and their people that they save, the odd picture she’s kept from 10,000 years ago when her planet was whole and her family alive.

Coran isn’t the best photographer, and most of his pictures are blurry, but it doesn’t stop him from taking a thousand every day. The benefit of this is that every so often one comes out looking nice, and everyone can compliment Coran on it and make him happy. He loves the feeling of validation.

Feeder insects for hedgehogs

Hedgehogs are omnivorous animals by nature but most of their diet consists of insects. While they’re not going to die if you don’t feed them insects, I personally think it’s an important part of their diet given their menu in the wild. And most hedgehogs absolutely love them! Some hedgehogs just won’t eat insects, but don’t give up when your hedgie ignores them the first couple of times. It can take up to a few weeks and several tries (or even longer) before they get they’re edible, especially when they are not used to it - but once they’ve tried them, they’ll go nuts for it!
Some hedgehogs don’t like taking new treats straight from you. Leave the insects in their food bowl during the night instead.
I never feed insects straight from my hands; I leave them in their bowls or use tweezers for the sake of my fingers. You don’t want your hedgie accidentally chomping down on you in their enthusiasm!

Live, freeze dried or canned?
Some people don’t like squirmy bugs but live insects are definitely the best option, so your hedgehog could be a good excuse to overcome your fear! They are more nutritious since you can gut load them before feeding, and they’re fresh. Freeze dried insects like mealworms can cause constipation, so feed them in moderation.

Store bought or wild caught?
It is not recommended to feed wild caught insects to your hedgehog. These can contain parasites and pesticides. You can buy live insects in lots of pet stores and there are webshops who sell them online.
Breeding your own insects is cheaper and not that hard (with most species). You can find lots of caresheets and tips online!
Take good care of your insects and give them enough food and water before feeding them to your hedgehog. Otherwise it’s just an empty snack.

Suitable feeder insects
Here are some common (and less common) feeder insects with pictures.

Mealworm (Tenebrio molitor, on the right) and superworm (Zophobas morio)

Probably one of the most well-known feeder insects, mealworms are easy to keep and easy to breed. If you don’t want them to pupate it’s best to keep them refrigerated. This will slow down their metabolism. It’s very easy to breed your own mealworms if you keep them at room temperature. Hedgehogs can eat the pupae and beetles as well.
Superworms look like giant mealworms and are harder to breed since they are less likely to pupate. Some people cut off the head before feeding them since they have pretty strong jaws.
Both mealworms and superworms are quite high in fat so if your hedgehog has trouble staying slim you shouldn’t feed too many meal/superworms.

House cricket (Acheta domesticus)

Another common feeder insect. This one is a great treat for hedgehogs since they are low in fat and most hedgehogs love hunting for crickets. They are easy to keep and easy to breed (at room temperature, or slightly higher). Crickets can be quite noisy!
They are available in different sizes so they are suitable for young hedgehogs as well.

Jamaican Field cricket and Black field cricket (Gryllus assimilis/Gryllus bimaculatus)

About the same size as the house cricket, but they are not so fast and jumpy. While assimilis is a pretty silent cricket, bimaculatus has one of the loudest calls.
They need higher temperatures in order to breed.

Both crickets in the pictures above are young ones.

Dubia roach (Blaptica dubia)

Probably the best feeder insect for hedgehogs together with crickets since they are low in fat. The Dubia roach is a tropical roach (so if they escape their enclosure they won’t survive) and needs to be kept at a minimum of 68 F. It should be warmer if you want them to breed. They breed pretty easily, don’t smell and make no sound. They can’t climb either so it’s hard for them to escape if you keep them in a glass tank or plastic tub.

Desert locust (Schistocerca gregaria)

A big insect, low in fat so suitable for every hedgehog although they are too big for young ones. They are quite hard to breed, need higher temperatures and it can be harder to gut load them since they only eat grass and plants.

Waxworm (Galleria mellonella)

These are the larvae of the Greater wax moth. They are high in fat and should be fed as an occasional treat only. You can keep them at room temperature or in the refrigerator so they don’t pupate.

Phoenix worm/calcium worm (Hermetia illucens)

There are several names for the larvae of the Black soldier fly but the most common one seems to be “Phoenix worm”. They are very rich in calcium and not too high in fat (somewhere in between crickets and mealworms). They also contain high levels of lauric acid, which is known to kill viruses and bacteria. These larvae are suitable for every hedgehog and a great option for smaller hedgies who need a low fat treat.

Butterworm (Chilecomadia moorei)

These “worms” are actually the larvae of the moth Chilecomadia moorei. They have a bit of a fruity/buttery scent, hence the name.
Since these moths are considered a pest outside their native Chile, the larvae are irradiated before being exported so they cannot grow into moths and breed. They’re best kept refrigerated.
These larvae are high in fat and should only be fed as an occasional treat.

Sun beetle (Pachnoda marginata peregrina)

The larvae of the sun beetle are quite big and really high in fat. They should only be fed as an occasional treat - it’s like giving your hedgehog a big bag of fries.
The beetles they turn into cannot be fed since they excrete a nasty tasting fluid when threatened, but they can be kept as pets and are easy to care for and very pretty! They need higher temperatures to breed and pupate.
They have strong jaws so it might be good to cut off the head before feeding them to your hedgehog.

Dendrobena (Dendrobena veneta)

Mainly used as a composting worm and as fishing bait, they should be kept at (low) room temperature. They’re low in fat and soft, so they make a nice treat next to insects like crickets and roaches.
