My friend, Dave, and I walked up the Turkey Run trail in the Catalina Mountains. We found a spot by Sabino Creek in an area that used to have a cabin.
We were fascinated to see a dragon fly (possibly a Blue eyed darner- aeschna multicolor) patrolling the stretch of stream that was in front of us. It flew fairly near the surface of the water, turning around at a little rocky area about six feet to our right, then doubling back to about six feet on our left, where it turned around just before reaching the part of the stream that was in deep shade. We were impressed with its ability to change direction. It seemed to us that it found a mate when it disappeared with another dragonfly for a short time, and then came back to continue patrolling the stream. At one point Dave stood astride the stream to see if that would alter its flight path. Apart from a brief detour, it resumed its course, at times passing right between his legs. When I got home I read that this insect spends years in the water, going through various changes, until the last summer of its life when it grows wings and takes to the air.
We also began noticing plants that are not native to this mountain range. We assumed that they had been introduced by the cabin owners. Years ago there had been 12 cabins along this trail, all of them now removed. Evidently when they were occupied their owners had created their own little gardens.
From where we sat we could see the leaves of Lily of the Valley – Convallaria majalis . a large patch of Day Lily – Hemerocallis fulva, a patch of ornamental grass, with green and white stripes, and Spearmint (mentha spicata). Behind us was a patch of Periwinkle – vinca major. We marveled that the cabins were removed decades ago, which means that all of these non-native species have survived all that time without anyone looking after them. Life is tough, even in the form of these fairly small plants.
