The shield bug Elasmucha grisea in inquiry-oriented teacher education focused on ethology
The shield bug Elasmucha grisea (Insecta, Heteroptera, Acanthosomatidae) is common and easily accessible species in our country. Maternal guarding of eggs and immature offspring against enemies with typical defense behaviour can be well presented in inquiry-oriented school education focused on ethology. Tis behaviour is well observable with the naked eye (or using magnifying glass). Tere are described four basic female reactions against trespasser with respect of disturbtion intensity (see pen-and-ink drawings). Maternal care is prolonged until the third instar of offspring. More informations are presented in quoted literary sources. Proposals of some simple indoor ethological observations and experiments in school insectaria are presented.
