It is native to Europe, and it is one of several closely-related and morphologically similar species of Melolontha called cockchafers, alongside ...
This research compared the genetic makeup of M. hippocastani to a different cockchafer beetle, the Melolontha melolontha. They demonstrated that both M. hippocastani and M. melolontha show considerable genetic diversity within subpopulations within sampling sites with minor effects of past bottlenecks possibly masked by current population sizes ...
The red-headed cockchafer or red-headed pasture cockchafer (Adoryphorus couloni [1] [2] or Adoryphorus coulonii [3] [4]) is a species of Australian scarab beetle in the genus Adoryphorus. It is a pasture pest in Victoria, New South Wales, South Australia and Tasmania. [ 1 ]
Cockchafer is a common name for several species of plant eating scarab beetles regarded as agricultural pests. It is most commonly used for several European species of the genus Melolontha: The common cockchafer (Melolontha melolontha) The forest cockchafer (Melolontha hippocastani) Other species referred to as cockchafers include:
Amphimallon solstitiale, also known as the summer chafer or European june beetle, is a beetle similar to the cockchafer but much smaller, approximately 20 millimetres (0.79 in) in length. They are declining in numbers now, but where found they are often seen in large numbers.
Common names for this genus and many other related genera in the subfamily Melolonthinae are May beetles, June bugs, and July beetles. [ 1 ] [ 2 ] They range in size from 12 to 35 mm (0.47 to 1.38 in) [ 1 ] [ 2 ] and are blackish or reddish-brown in colour, without prominent markings, and often rather hairy ventrally.
European rhinoceros beetle European rhinoceros beetle – three stages from larva to adult: larva (back), pupa (center), and imago (front). The Dynastinae are among the largest of beetles, reaching more than 15 centimetres (6 inches) in length, but are completely harmless to humans because they cannot bite or sting.
Bed bugs were a serious problem at US military bases during World War II. [80] Initially, the problem was solved by fumigation, using Zyklon Discoids that released hydrogen cyanide gas, a rather dangerous procedure. [80] Later, DDT was used to good effect, though bedbugs have since become largely resistant to it. [80] [81] [82]
