Insect compound eyes consist of a mosaic of tiny optical units, or ommatidia ( 1). This design method opens up additional vistas for a broad range of applications in which wide field motion detection is at a premium, such as collision-free navigation of terrestrial and aerospace vehicles, and for the experimental testing of insect vision theories. The prototyped artificial compound eye possesses several characteristics similar to the eye of the fruit fly Drosophila and other arthropod species. Following this method, we have prototyped and characterized an artificial compound eye bearing a hemispherical field of view with embedded and programmable low-power signal processing, high temporal resolution, and local adaptation to illumination. The design consists of three planar layers of separately produced arrays, namely, a microlens array, a neuromorphic photodetector array, and a flexible printed circuit board that are stacked, cut, and curved to produce a mechanically flexible imager. Here, we describe a unique design method for biomimetic compound eyes featuring a panoramic, undistorted field of view in a very thin package. Engineering a miniature artificial compound eye is challenging because it requires accurate alignment of photoreceptive and optical components on a curved surface. Compound eyes are ideally suited for fast panoramic motion perception. This Key is based on the Keys that can be found in the following books.In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, as well as high temporal resolution in a tiny package. First pair of legs raptorial (used to grasp prey) and held close to the body at rest = Praying Mantidsįront legs not like this and body flattened = Cockroaches.

Head narrower than body: sucking mouthparts: abdomen often with a pair of tubular outgrowths ( cornicles) near hind end: insects found on growing plants = Hemiptera Head a wide or nearly as wide as body: biting mouthparts: insects often found among dried materials = Psocoptera.Insects 5mm long, clothed with flattened hairs and scales: vestigial wings present = Lepidopteraīody usually Body grasshopper-like, with enlarged hind legs and pronotum extending back over abdomen =.Insect wingless or with poorly developed ( vestigial) wings. Start at Question 1 and follow the links until you've identified your insect. Non-members can use the Bug Club discussion forum however membership of this forum is not restricted and we cannot guarantee the help/advice offered. The AES cannot be held responsible if the Key provides an incorrect identification, it is intended as a guide only - if you require a species level identification then please use our identification services or send the insect with comprehensive details of where you found it to the Entomology Department of your nearest University or Natural History Museum. An explanation of many of these terms can be found on the Insect body structure page or within the Insect fact files section. The Key uses some specialised terms to describe specific parts of an insect's body.The Key may not be successful if used to identify insects outside the UK although in most cases it should still produce a correct identification.The Key will only work for adult insects (the imago), it is not intended for juvenile insects, larvae or caterpillars so make sure you are trying to identify an adult insect.These are still included in the key in order to make the key as useful as possible. The Key also refers to some groups (such as the Protura, Diplura and Collembola) which are considered to be non-insect hexapods rather than insects.
