Scotch argus Adults fly from June to August. The eggs are laid singly on the leaves of grass. The larvae hatch after two weeks. The hibernating larva is reported to feed on "Agrostis", "Dactylis", "Poa annua", "Bromus erectus" and other grasses. In Scotland the main host plants are purple moor-grass ("Molinia caerulea") and blue moor-grass ("Sesleria caerulea"). Scotch argus The Scotch argus ("Erebia aethiops") is a butterfly of the family Nymphalidae. In spite of its English name "argus", it is not a close relation of the brown argus nor the northern brown argus. Subspecies include: "Erebia aethiops" is widespread in the Palaearctic
Argus laser groups of amplifiers and spatial filters arranged along the beamlines, each one boosting power until it reached a total of about 1 kilojoule and 1-2 terawatts per beam. These intensities would have been impossible to achieve without the use of spatial filtering. Argus was designed primarily to characterize large laser beamlines and laser-target interactions, there was no attempt to actually achieve the fusion ignition state in the device as this was understood to be impossible at the energies Argus was capable of delivering. Argus however, was used to further explore higher yields of the so-called "exploding pusher" type targets and
