The juniper hairstreak is one of our more elusive butterflies; in spite of the fact, it ranges across most of the state except in portions of Southwest Georgia. This is unfortunate because this small (wingspan roughly one-inch), butterfly possesses unique beauty. When you see a juniper hairstreak, the thing that jumps out at you is the jewel-like olive green color that covers most of its wings.
Juniper hairstreaks are often difficult to find anywhere, let alone in backyards. However, last summer I saw more juniper hairstreaks in my yard than I had seen in my entire life. My good fortune is appears linked to my transplanting mountain mint plants in four locations in my backyard. During much of August 2020, I could consistently find juniper hairstreaks nectaring at the mountain mint’s tiny blooms.
Prior to last summer, I would only occasionally find juniper hairstreaks nectaring on the blossoms of white clover in my backyard. However, I would often go a year or more without seeing one.
JUNIPER HAIRSTREAK ON MOUNTAIN MINT
I did not understand why this is the case since several large red cedars grow in my large backyard. Red cedar is the juniper hairstreak’s host plant. It seems juniper hairstreaks do not venture far from the trees, preferring instead to spend the majority of its time in the trees aromatic foliage.
In fact, I have often read that the best way to see a juniper hairstreak is to flush one by shaking a limb or tossing a dead branch in the into the canopy of a red cedar. Although I have tried this trick many times, it only worked once.
The juniper hairstreak nectars on a variety of flowering plants, although for some reason, I have never seen a juniper hairstreak feed on any of the large array of nectar-bearing flowers in my yard. That is until I planted mountain mint.
If you long to see a juniper hairstreak and red cedars grow nearby, you might want to plant mountain mint in your yard. The native is hardy an easy to grow. If you do add this plant to your yard, set it out in a place where it will not compete with other nectar plants, as it will spread.
Once you spot the first juniper hairstreak in your yard, you will wish you had made its acquaintance a long time ago.
