Step 1:

For this guide I have chosen to use a symmetrical design, so start by drawing a vertical line and then work a design on one side of it.* Start by drawing two ovals, the top one being the largest like in sample 1.* Once you have your basic butterfly shaped wings down you can now start to make up a design within and around it like in sample 2 below.

Step 2:

Go crazy and have fun with it! I like my tribal butterfly tattoos spikey and sharp with curls like below in sample 3, you may have a different idea in mind.

Step 3:

Then once you’re happy with your design trace over it and flip it like in sample 5 below.

Step 4:

Now render it however you like.
