The widow skimmer dragonflies begin to visit my yard more frequently, again This means it’s over 100ºF, and it’s mid July. As soon as I fill up the bird bath and water the garden, my little dragons come over for a visit and check out, what I’m doing. They love to hang out in my yard until sunset. And the following evening, the dragonflies show up again. I love Texas Summers. Usually, when it gets that hot, the humidity goes away.
