Over the past few days, an Eastern Cicada-killer Wasp (Sphecius speciosus) has been bringing dead cicadas to this hole in our patio, trying without much success to put them into that hole. We think that that hole leads to a small cavern, perhaps excavated by a chipmunk.

缺乏地點資訊描述
Some of the original trees reaching Bermuda evolved into distinct new, endemic species that occur naturally nowhere else, e.g., Bermuda Cedar (Juniperus bermudiana) and Bermuda Palmetto (Sabal bermudana); however, scale insects introduced during the Second World War construction of United States Navy and United States Army Air Forces bases devastated the forests, killing over 99% of the Bermuda cedar ("The Blight", or "The Cedar Blight"), and the salt-tolerant Casuarina equisetifolia was planted as a replacement species, and then a small number of Bermuda cedars have been found to be resistant to the scale insects

The genetics are unclear but I have 2 yellow flowered reds among a thousand reds on my property. I have never seen them make a nut. So their fertility status remains unclear.

This is Arisaema species 2, per Weakley's new Arisaema key (to be released later this year). It had leaves that were glaucous below, and a spadix that measured 4 mm across.

joeysantore描述
8' diameter breast height. This tree is likely centuries old, indicating that although it's on a canal there was probably a creek or waterway here before the canal was built.
