Blood beetles eat mosqitoes and algae
Yes, the beetles answering to the common name of 'black beetles' are in fact black in color.
Insects that have red blood when killed are typically arthropods, such as beetles, grasshoppers, and true bugs. Their blood contains a pigment called hemolymph, which gives it a red color.

If color is an inherited trait in beetles and birds preferentially eat brown beetles over green ones, then natural selection will likely favor the green beetles. Over time, this could lead to an increase in the population of green beetles, as they are less likely to be predated. Consequently, the population's genetic makeup will shift, resulting in a higher frequency of the green color trait in future generations. This illustrates how selective predation can drive evolutionary changes in a species.
To differentiate between brown and black beetles for identification, look at the color of their exoskeleton. Brown beetles have a reddish-brown or tan color, while black beetles are dark in color, often shiny or matte black. Additionally, observe any patterns or markings on the beetle's body, as these can also help distinguish between the two.
Flowers pollinated by beetles tend to have strong, fruity or fermented odors that attract beetles. These flowers are often dull in color, such as white or cream, as beetles do not rely on color cues for pollination. Additionally, beetle-pollinated flowers may have sturdy structures and surfaces for the beetles to easily crawl and forage for nectar and pollen.
Varied carpet beetles get their name from the rainbow of color on their backs. It can take up to three years for them to grow from an egg to an adult. Adult beetles only live between 13 and 44 days! xxSunshineheart1
