This is a very unusual insect in Baltic Amber. It is a large Moth (Lepidoptera) from Russia. This specimen could be a Butterfly - it has segmented antennae! The insect has nice detail - the large, spread wings are beautifully preserved. The moth is easily seen trapped within the large amber piece. This is a fine example of a fossil Moth (Butterfly?) entombed in Baltic Amber (large close-up photo is included for free).
