So if there are leaf beetles, why are there other kinds of beetles? !!111!!!eleven! :p

And why so many kinds, perhaps even more than eleven?

Maybe, but only be several orders of magnitude.

https://en.wikipedia.org/wiki/Leaf_beetle The family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but only some of them are listed below and the precise taxonomy and systematics are likely to change with ongoing research.
Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the 4th tarsal segment is very small and hidden by the 3rd.[2] As with many taxa, there is no single character that defines the Chrysomelidae; instead it is delineated by a set of characters.[3] Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles.
Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, for example the Colorado potato beetle (Leptinotarsa decemlineata), the asparagus beetle (Crioceris asparagi), the cereal leaf beetle (Oulema melanopus), and various flea beetles, and a few act as vectors of plant diseases. Others are beneficial due to their use in biocontrol of invasive weeds. Some Chrysomelidae are conspicuously colored, typically in glossy yellow to red or metallic blue-green hues, and some (especially Cassidinae) have spectacularly bizarre shapes. Thus, they are highly popular among insect collectors.
...Comment:
I would suppose that the "fractal" ability of "evolution", explains the quasi symmetrical pigmentation, on most of these beetles wings/backs! It does impress me, that the bright red and black coloration's, seem to be more of an attraction than a camouflage! Please somebody explain why they are not a delicacy! They must have some bad "flavor"!

If "Biblical kinds" ("baramins") are families, then those tens of thousands of species of leaf beetles are all of one kind.

Some leaf beetle larvae and adults are toxic due to the plants they eat. Note that the one in the picture looks like a ladybug at first glance. Ladybugs are definitely toxic, and wear "warning colors" to ward off predators. So whether or not the bug in the picture would be toxic to a bird, the colors say "Stay away!" A number of animals mimic others to deter predators, as the cost of mimicry may be less than the metabolic cost of carrying the toxin themselves, which may not be an evolutionary genetic option for them anyway. Scarlet king snakes, Viceroy butterflies, and a number of other insects mimic dangerous species. I had a pet bull snake that mimicked a rattler with coloration and by vibrating her tail in grass or leaves, which produced a convincing enough rattle to make most predators think twice.

And evolved bloody damned fast after the "Flood". Except if you're a YEC, then you can't call it evolving.

Well folks I am no Bible freak, but colors are a big problem...!
Can somebody tell me if "red" cherries and apples and tomatoes are bad...?!
It is rather "tricky"...!
These Beatles must have a "shit" smell to them...!
Anyway, the intelligence of humans is limited by their capacity of perceiving true reality! And if the best explanation for life's beings is Evolution, it must be so that everybody does not get suicidal or too violent, not believing in anything after this life! A political/social agenda to the opposite of Religion!

Groan.
George, it is true, is clearly no Bible freak. The qualifier is unnecessary.

I guess its bright color is a way of telling predators to leaf me alone?
