Margarinotus ephemeralis is a species of clown beetle in the family Histeridae. [2] [3] [4] It is currently only known from southern California. [1] [3] [4]
The body is oblong oval and measures 3.8–5.2 mm (0.1–0.2 in) in length (from anterior margin of pronotum to posterior margin of elytra) and 2.7–3.2 mm (0.1–0.1 in) in width. The elytra have five striae; the first three are complete, the fourth is complete or slightly abbreviated, and the fifth is present in apical half or less, and may be nearly absent. The prothorax has convergent, arcuate sides; the pronotum has a single lateral stria. Margarinotus ephemeralis is very similar to Margarinotus remotus , but differ in the pronotal punctuation. [1]
Some specimens were collected from the burrow entrances of California ground squirrel, and others from temporary pools where they presumably had been flooded out of burrows. This species might be an obligate inquiline of California ground squirrel burrows. [1]
Histeridae is a family of beetles commonly known as clown beetles or hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other hister beetles, they must be isolated when collected.
Margarinotus brunneus is a species of beetles belonging to the family Histeridae. They seem to be a vibrant blue colour, but when their shell is under a microscope it appears a pastel red colour. This is due to “Delton’s colour theory of aphropods.”
