Highlights•Image forming compound eyes were present in Cambrian predatory arthropods
(~ 520 mya).•Several arthropod predators have evolved high-resolution single-chamber …

Despite their relatively simple nervous systems, insects display a rich behavioural repertoire,
in which vision plays a major role. In the past two years, much knowledge has been gained …

The compound eyes of insects exhibit stunning variation in size, structure, and function,
which has allowed these animals to use their vision to adapt to a huge range of different …

Very few visual systems diverge fundamentally from the basic plans of well-studied animal
eyes. However, investigating those that do can provide novel insights into visual system …

Highlights•As insects are small they must optimize target visualization solutions.•Insects
visually determine target suitability for efficient pursuit.•Insect target neurons display …

The compound eye of insects imposes a tradeoff between resolution and sensitivity, which
should exacerbate with diminishing eye size. Tiny lenses are thought to deliver poor acuity …

In the words of Wehner (J Comp Physiol A 161: 511–531, 1987) who first coined the term
“matched filter” in the context of sensory systems, matched filters “severely limit the amount …

Despite being equipped with low-resolution eyes and tiny brains, many insects show
exquisite abilities to detect and pursue targets even in highly textured surrounds. Target …

Prominent eyes and antennae serving vision and olfaction are distinctive features of many
arthropods, while underlying ganglia such as insect optic lobes, antennal lobes and …

For proper function, vertebrate and invertebrate visual systems must be able to achieve and
maintain emmetropia, a state where distant objects are in focus on the retina. In vertebrates …
