Cliff Stiletto

The Cliff Stiletto is a member of the stiletto fly family Therevidae, a family of predatory flies whose larvae inhabit soil, sand, and decomposing wood. Stiletto flies are slender, pointed-bodied dipterans with a sharp-tipped abdomen, giving rise to the family name. Adults are typically found basking on sun-exposed surfaces including cliff faces, rocky ground, and sandy banks, where they hunt other small insects. The larvae of most Therevidae species are predatory soil-dwellers, feeding on other invertebrate larvae in loose, sandy, or gritty substrates. Cliff-associated species may exploit the loose, dry substrates in cliff-face crevices and the compacted soils of cliff bases as larval habitat. The family Therevidae is distributed globally, with greatest diversity in xeric and Mediterranean-climate regions where open, sandy, or gravelly habitats are prevalent. Stiletto flies as a group have received relatively little study compared to larger fly families, and the taxonomy, host associations, and conservation status of many species remain poorly documented. Adults are often short-lived and are found only during the warmer months when insect activity is highest on cliff and rocky habitat.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
