Coccinellidae Coccinellidae Coccinellidae () is a widespread family of small beetles ranging in size from 0.8 to 18 mm (0.03 to 0.71 inches). The family is commonly known as ladybugs in North America, and ladybirds in Britain and other parts of the English-speaking world. Entomologists widely prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs. The majority of coccinellid species are generally considered useful insects, because many species prey on herbivorous homopterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect
Linker histone H1 variants core domain, while the N- and C-termini are more divergent. At the same time H1 orthologs among mammals are highly conserved across the whole protein sequence, for example human and mouse H1.4 share 93.6% sequence identity. The extent to which individual H1 variants can be redundant and what their distinct functions are isn’t yet clear. The fact that many individual H1 variant knockouts in mice are viable and show compensation by other H1 variants seems to support the hypothesis of redundancy. However, many lines of evidence suggest specific functions exist for H1 variants. For example, individual H1 variant knockout mice
