Mainly observable in birds and mammals (and also a few plants), it is related to the surface area to volume ratio. In warmer climates, body heat needs to be released rapidly while in colder climates it behooves the animal to store the heat (perhaps counterintuitively, larger animals emit less body heat).
In this case, Florida Baldies average just over nine pounds, while in Alaska they top the scales at fifteen. No matter what the size, Bald Eagles are still majestic!
I viewed this colorful insect with a wary eye since red and black tend to be warning signs in nature. Turns out that Common Thread-waisted Wasps (Ammophila procera) are relatively harmless as the adults mainly feed on nectar. Vocab word of the day: petiole is the narrow waist in between the abdomen and thorax.
Unlike the male, the female has an ovipositor, which is used for egg-laying (and stinging, when necessary). She does all her parenting upfront: paralyzing a caterpillar, dragging it into a sandy burrow, inserting a single egg, and sealing the burrow, before flying away.
When the larva hatches, it consumes the (immobile but still alive) caterpillar from the inside out. Makes me glad I’m not a caterpillar!
This carpenter bee’s large size caught my attention as she* whizzed by my head on the way to a flower. If I was an entomologist, I would be able to tell you which of the two species of Xylocopa (that reside in Florida) it was, but it’s a bit tricky to discern the difference.
One would have to determine the distance between the eyes, the number of antenna segments, types of submarginal cells in wings, and abdomen and thorax color and pubescence. Fascinating details, I’m sure but I was too enthralled with her colorful, diaphanous wings and the way they resembled a stained glass window. Just stunning!
*I am fairly certain this was a female since the males tend to sport a bit of yellow on their thorax.
Though the brunt of the storm was 300 miles away, Hurricane Laura churned up the water along Florida’s Gulf Coast. Scattered along my beach are brown clumps mixed with shells. Though they look like rocks, the brown lumps are actually soft and squishy tunicates.
Affectionately called Sea Squirts, tunicates are colonial bottom dwellers that attach to hard surfaces (including abandoned shells). The wave action also tossed up a bunch of sea urchins (and by now you should know how I feel about them).
We’ve received a sneak peek at life from the benthic level of the sublittoral zone. Since they were deposited above the normal high tideline we will get to enjoy the delightful aroma as they decay in the sand.
