Sexual activity in Coccinellidae (Coleoptera): a review [PDF]
European Journal of Entomology, 2000 Although there are few studies of the sexual life of coccinellids these phenomena have attracted the interest of isolated groups of coccinellidologists. Probably the most important finding is that at least some coccinellid species (Adalia bipunctata and Harmonia axyridis) do not mate at random with the females prefering certain males.

The evolution of food preferences in Coccinellidae
Biological Control, 2009 Despite the familiarity and economic significance of Coccinellidae, the family has thus far escaped analysis by rigorous phylogenetic methods. As a result, the internal classification remains unstable and there is no framework with which to interpret evolutionary events within the family.

Male-killing bacteria in insects: mechanisms, incidence and implications [PDF]
, 2000 Bacteria that are vertically transmitted through female hosts and kill male hosts that inherit them were first recorded in insects during the 1950s. Recent studies have shown these "male-killers" to be diverse and have led to a reappraisal of the biology
