That's because you need to import the private key from your eth address before you will see it. If you want to verify it is there you can look up your eth address on a ubiq block explorer.

In order to recover the coins you need to export the eth wallet private key first so you can import it to your ubiq wallet. Unfortunately I don't have step by step instructions for you and it depends on which particular wallet you are using. You can probably find info in a FAQ for the wallet you are using with some searching.

For example if it is a ledger nano hardware wallet a quick search comes up with this:

You should be able to find similar guides for mist/geth, parity, myetherwallet, jaxx, etc. with some searching. Same goes for finding a guide for the second step of how to import keys into a wallet. Google is your friend.
