REFERENCING??

I've got a question to anyone that's willing to help:

Is it acceptable to use number as well as formal (stating authority in full) referencing simultaneously in-text? E.g. "Butterlies exist as metapopulations [3]. According to Jackson (1993) it is the most prevalent population structure."
(Bear in mind that these are two different sources).
