[00:00:00]Hello, welcome beetle people. And today is my update on my three rhino beetle larvae, specifically my Enzylotropes philippinensis peregrinus rhino beetle larvae. Gosh, that is a hard scientific name. So, first one here is at 14.3 g. Unfortunately, they've actually lost weight. Before, they were over 16 g. They appear to have lost a lot of this weight because they spent a lot of time wandering looking for a suitable place to make a pupa chamber.

[00:00:29]All right, and now time for the smallest one.

[00:00:32]Now, this one has been kind of weird.

[00:00:33]Even after all this time, this one is still much, much smaller than its siblings. As you can see it right here, they are only 6.5 g. That is nearly a 10 g difference compared to its other siblings. So, I'm a little worried about them.

[00:00:47]All right, to now here for the last and final rhino beetle. I know this one has already made a pupa chamber, so I'm just going to carefully dig it up until I find it. There we go.

[00:00:56]Let's open up the hole a little bit so we could take a look inside.

[00:01:02]So, taking a look, I was a little bit surprised to see, but this one is actually a female. They don't have their horns. This individual was around 15 or so grams the last time I weighed them.

[00:01:12]So, I'm just going to cover them up, make sure they stay moist, and wait for them to emerge.

[00:01:16]One thing I had noticed is that rhino beetles tend to have a much longer pupation period compared to stag beetles. Stag beetles are generally around 1 month. Rhinos seem to be longer than that.

[00:01:27]And looping back to the first larvae from the video, this is about 1 month later. As you can see, he has finally decided to pupate. And because he has a bottom and upper horn, I can tell that he's a male. Unfortunately, because he did some wandering and lost a good amount of weight, he's going to be a bit of a smaller male. This is somewhat unfortunate, though this species is already really small, and they are very cute either way.

[00:01:49]I also really like how the light reflects off the pupa. It gives them a nice cool yellow outline.

[00:01:55]That's all for this update, and happy beetling.
