Your insect in the pictures is a Soldier Beetle, perhaps in the genus Polemius. These beetles feed on other insects, nectar, and pollen, they do not chew leaves. The damage to those leaves could be from a variety of other insects; try checking at night also.

This looks similar to the rescuegrass I fight in my garden. It comes up everywhere in March or April and goes to seed by May. Rescuegrass

Nice, and really unique. You will just have to keep your eyes open for something that will work with that. Take the measurements down for what will work, you may get lucky and find something. The mirrors got separated on those vanities for hanging separately or just got broken. If you can find something maybe a simple round mirror with a black frame would work hanging on the wall above it. Before you try and strip and refinish check out re-amalgamation of varnish finishes. Google term or go to YouTube. Hint, if you can use this technique do it with a light hand if you want to retain patina. Also, don't remove patina from the drawer handles, just remove and give them a good scrub with soap and water. Here is one of many videos...I've used what is called mineral spirits, it's called whatever the guy uses in England, same stuff. Just check out YouTube videos. https://youtu.be/F9SsSF1Qv_Q Maybe not even use steel wool as this guy recommends. First try a gentle approach with a white cotton cloth dipped in mineral spirits. The process basically disolves the varnish, removes some, then the varnish re-hardens/drys. It happens rather quickly too. That is if it's natural varnish that was used, which is more likely than not. Doing a test spot will quickly tell you if it is varnish rather than polyurethane, basically nothing much will happen to finish if poly.

@ken_adrian Adrian MI cold Z5 RDD is a serious and scary disease of roses. ”Rose rosette disease (RRD) causes elongated rose shoots, leaf distortion and an unusual red or yellow mottling of the leaves.”
