It s not from a bug. Rodent , probably. Or feline.

Hi Angelina. I know you didn't ask about this so I hope you don't mind me saying... Could your plant be an Echevaria? The top leaves remind me of my E. Perle von Nurnberg, but if so, it is very etoliated and could use brighter light as the plant's normal growth habit should be a tighter rosette with proper light.

*echeveria. I think ive seen you misspell it earlier. I caused confusion when i used to spell mihailovichii instead of mihanovichii.

It is a perle von nunberg, and yes its etiolated. However, the user has asked about a more immediate problem, one of animal origin.

mouse, squirrel, slug ???

Slugs should leave trails..... and they dont leave bite marks.

The bites are near identical too.

I'm guessing mouse based on height.

I would go hunting for a worm. Typically, they chew on the leaf margins and they get inside thank to moths laying their eggs. Rodents, slugs and snails are more of a nuisance outside

Slugs don´t leave bite marks? - Well those in my garden damn well do - and so do those on line.

Squirrels, mice, and rats usually leave marks from their front teeth.

Find the pest and then figure out how to get rid of it!!

I used a wifi security camera with motion detection and video playback to figure out what was attacking my succulents and how they were getting to them.

Spanish fly, at this point, can you really say that a large slug(because if its that symmetrical and proper curved needs to be large)managed to hang off a what i can guess is leaves at 30-40 cm height?

SoCal, im just pointing out my flaws, that i notice in other people. Sometimes i misspell out of laziness or fatigue, sometimes i blame autocorrect .As for species...... memory serves best. I try to get the genera, since they are more important.

All I can say, Stefan, is I have better things to do than argue trivia. In my long experience slugs are a pest - they EAT plants - and they do it by BITING into them. Nothing more whatever to say.

Here is a video I took, all in just a single day two years ago:

We don't really have giant slugs here, thankfully. =)

Wow ewwmayo. Hungry, destructive little suckers. Were you able to stop them from destroying your plants?

Id kill the squirrel. It might teach its young to do the same. Like bears and garbage.Sad, but efficient.

Eventually, I was able to deter them with two motion detecting sprinklers that provided good coverage of my grow area.

The problem with killing them is that others will just move in and start damaging your collection again. Squirrels in particular are quite territorial.

For rabbits, mice, and rats some people use fabric or metal mesh to block them out. This is commonly done for people with vegetable gardens.

Thanks for all the suggestions so far!

It seems from the posts that the culprit is either a rodent or a worm, of both which I will definitely keep an eye out for.

Just for a size clarification, my plant is around 13 cm tall and the bite marks seem to measure approximately 0.6cm.

Lol at the squirrel in that video. That little bastard!!!! Every summer the same happens to me, I come home to find bite marks on leaves and pumice dug out of the pots. I’ve started using a red pepper spray and that seems to work.

I tried to help my neighbour with critter ridder (pepper spray) last summer. Got the squirrel but the wind got me in the eye with some overspray. Learned my lesson pretty quick!
