Exema is a genus of leaf beetles in the tribe Fulcidacini. They occur worldwide, [1] with 9 species in North America for example.
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.
Blister beetles are beetles of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematically colored, announcing their toxicity to would-be predators.
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily.
Neochlamisus is a genus of leaf beetles in the tribe Fulcidacini. They are members of the case-bearing leaf beetle group, the Camptosomata. Measuring 3–4 millimeters in length as adults, they are cryptic, superficially resembling caterpillar frass. Seventeen, sometimes 18 species are presently accepted in this genus, all of them occurring in North America.
The Fulcidacini, sometimes known as the warty leaf beetles, are a tribe within the leaf beetle subfamily Cryptocephalinae, though historically they were often treated as a distinct subfamily, Chlamisinae. 11 genera with altogether about 400 species are currently placed here; some four-fifths of the species are found in the Neotropics, but the rest is distributed over all other continents except Antarctica.
The Galerucinae are a large subfamily of the leaf beetles (Chrysomelidae), containing about 15,000 species in more than 1000 genera, of which about 500 genera and about 8000 species make up the flea beetle tribe Alticini.
The Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
The Cassidini are a tribe within the leaf beetle subfamily Cassidinae. The Cassidini comprises approximately 40 genera worldwide, and is one of the largest tribes in the subfamily, containing most of the genera and species known collectively as "tortoise beetles". The subfamily names Cassidinae and Hispinae were both founded by Gyllenhal in the same 1813 book, but following the Principle of the First Reviser, Chen in this case, priority is given to the name Cassidinae.
Chrysomela is a genus of leaf beetles found almost throughout the world, but not in Australia. It contains around 40 species, including 7 in eastern and northern Europe. It also includes at least 17 species in North America, including the cottonwood leaf beetle Chrysomela scripta.
Exema elliptica is a species of warty leaf beetle in the family Chrysomelidae. It is found in North America.
Glyphonyx is a genus of click beetles in the family Elateridae. There are at least 50 described species in Glyphonyx.
Exema gibber is a species of warty leaf beetle in the family Chrysomelidae. It is found in North America.
Chlamisus, sometimes known as the cloaked warty leaf beetles, is a genus of warty leaf beetles in the family Chrysomelidae. There are more than 90 described species in Chlamisus.
Exema canadensis is a species of warty leaf beetle in the family Chrysomelidae. It is found in North America.
Exema deserti is a species of warty leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Exema dispar is a species of warty leaf beetle in the family Chrysomelidae. It is found in North America.
Pachybrachis othonus is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America.
Exema byersi is a species of warty leaf beetle in the family Chrysomelidae. It is found in North America.
Exema neglecta is a species of warty leaf beetle in the family Chrysomelidae. It is found in North America.
Exema conspersa is a species of warty leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
