In my garden, butterflies often owe their early spring survival to some unlikely sources- the larvae of aspen borer beetles and poplar clearwing moths.

You may be wondering what they the butterflies ares eating, because if you have been looking around for the last few weekend, you'll have noticed that not much is flowering yet. As a result, this is one of the most critical times of the year to support butterflies in your garden (or at least attract butterflies to your yard).On warm March days you can see the sap running (slowly) out of the holes in the trees, and when the first butterflies emerge this is where they go to eat.

If you want pollinators, plant a lot of native plants and get out of the way!
