New Cattleya developed mold and sunburn?

[DesignerofBeauty]

Hello All!

I'm a bit new to orchids, so please pardon any lack of basic information.

I just received a Lc.Tropical Chip 'Andromeda' in the mail a week ago.

Today, I noticed that one of the leaves has what appears to be sunburn. Additionally, I noticed some white spots in the medium. I'm confused as to how this all happened.

Here's some background information:
The plant was shipped in 3 days from Hawaii to Rhode Island. It was left in the cold (mid 20's) for about 2 hours, but it did have heating packs inside the package. It was packed very very well, so I wasn't concerned. I noticed that the medium was moist, so I haven't watered it since it has arrived. I did notice that there was some moss growing on the medium, and a black centipede/caterpillar with a red stripe down it's back. I killed the bug, and haven't seen another since. Additionally, I noticed that a section of the plant had significantly lighter leaves. These leaves are a bit glossier than the others, so I suspected that it was a new growth.

The lighter leaves have developed what appears to be sunburn. This wasn't present at arrival. However, the orchid is placed on the same windowsill as another cattleya . The other cattleya doesn't receive adequate sunlight, as it's leaves are too dark. In fact, I'm waiting for artificial lighting to come in the mail as I write the message. Thus, I don't know how it received sunburn.

Additionally, I haven't watered the plant since it arrived. I'm clueless as to how it might have developed mold.

Any ideas?

Thanks!!
