The oak eggar (Lasiocampa quercus) is a common moth in the family Lasiocampidae found in Europe and northern and western parts of Asia. The larvae feed on a wide variety of plant species, low down, including blackthorn, hawthorn, viburnum, dogwood, ivy and ling, but are not known to feed on oak. They can be infected by baculoviruses, which change their behaviour and cause them to climb out of the protection of low scrub and leave them open to predation, facilitating the spread of infection. Oak eggar larvae eventually pupate on the ground inside a silken cocoon, the exterior of which is hard and yellowish, and resembles an acorn, from which the common name "oak eggar" is derived. This oak eggar larva in the form of a fourth-instar caterpillar, with a body length of 53 millimetres (2.1 inches), was photographed on a branch in Keila, Estonia. The photograph was focus-stacked from 59 separate images.Photograph credit: Ivar Leidus

When to use subpages

A subpage is a page that is stored "under" another page, and includes the parent page's name in its title, followed by "/" and the subpage's name. For example, User:Eloquence/Favorite Wikipedia quotes. When you visit a subpage, you will see a backlink (aka breadcrumb) near the top of the page back to the parent page.

Subpages can be useful for organizing and archiving project content, and for creating workspace under a user account. On a parent page, you can create a link to one of its subpages by typing [[/Name]]. If you end the link with a slash, e.g., [[/Name/]], the slashes are hidden in the output.

Articles don't have subpages. That is, subpages are not enabled in the article namespace, because many articles might qualify as subtopics of more than one topic. Instead, follow article naming conventions and include links to related subjects in the text.

For the subtopic structure of subjects, see Portal:Contents/Outlines.
