His inaugural volume was the classic 1934 book A Field Guide to the Birds, published (as were all subsequent volumes) by the Houghton Mifflin Company. The PFG series utilized what became known as the Peterson Identification System , a practical method for field identification which highlights readily noticed visual features rather than focusing ...
The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. The series also includes several Check Lists of British Insects. All books contain line drawings, with the most recent volumes including colour photographs.
Intended for primary and secondary school level readers, the first books were field guides illustrated by James Gordon Irving, with such titles as Birds (1949), Insects (1951), and Mammals (1955). The series later expanded beyond identification guides to cover a wider range of subjects, such as Geology (1972), Scuba Diving (1968) , and Indian ...
Beetle collection at the Melbourne Museum, Australia. Insect collecting refers to the collection of insects and other arthropods for scientific study or as a hobby. [1] Most insects are small and the majority cannot be identified without the examination of minute morphological characters, so entomologists often make and maintain insect collections.

The heaviest of this widespread, varied complex of insects is the Little Barrier Island giant weta, Deinacrida heteracantha, of New Zealand; one specimen weighed 71 g (2.5 oz) and measured nearly 10 cm (3.9 in), [2] giving it one of the largest insect weights ever known. These heavyweight insects can be over 9 cm (3.5 in) long. [8]
The adult insect, known as an imago, is 2 to 5 cm (1 to 2 in) in total length in most species. The largest, the empress cicada ( Megapomponia imperatoria ), has a head-body length around 7 cm (2.8 in), and its wingspan is 18–20 cm (7–8 in).
Adults are small (< 2 millimetres (5 ⁄ 64 in)) to medium-sized insects (- < 10 millimetres (25 ⁄ 64 in)). Larger Diptera are rare, only certain families of Diptera Mydidae and Pantophthalmidae reach 95–100 millimetres (3 + 3 ⁄ 4 –4 in) wingspan while tropical species of Tipulidae have been recorded at over 100 millimetres (4 in).
