Subfamily Aegialiinae has three British species, all small (4-5mm), elongate and associated with decaying vegetation in dry, sandy areas. Those developing within ant and termite nests tend to be highly specialized with their life-cycle intimately associated with the host. Scarab Beetles (Family Scarabaeidae) The family Scarabaeidae is one of the largest beetle groups, with over 19,000 species worldwide and about 1,400 in North America. 窶｢ Beetles of the Scarabaeidae family (dung beetle) roll dung into a ball as food and as a place in which to lay eggs.

In general the dynastines and dung beetles display such dimorphism while the chafers do not. The beetle pushes a roller device to unlock the box and climb in. Though we are uncertain of the exact species, we suspect it might be the larva of a Green June Beetle, Cotinis nitida, which you can find pictured on BugGuide. Many species, including many large tropical dynastines, are attracted to light and may occur in huge numbers. The large brown chafer Melolontha melolontha (L.) (cockchafer or maybug) is a member of this subfamily and can occasionally swarm in large numbers. Includes chafers with unequal meta-tarsal claws. Valgini Mulsant, 1842 (Cetoniinae Leach, 1815) include termitophiles. It is a very rare species of south-east England associated with cattle dung on sandy soils. Only the male possesses the ‘antlers’, which are infact enlarged jaws. These species were chosen due to their important pest status in Europe, but they also serve as model organisms for white grubs in general. They are often found hiding or sheltering in plant pots, under … All images on this website have been taken in Leicestershire and Rutland by NatureSpot members. Scarab beetles (including the chafers and dung beetles) have characteristic antennae in which the final segments have fan-like extensions. All are associated with decaying vegetation on dry and sandy soils and all are vary local. In general competition for dung is very strong, the rollers will often fight over a dung-ball and sometimes a ball is covered in males and females fighting for possession, and even during burial where one sex will stand guard while the other digs there will be constant attacks from others, even when the dung is within the burrow. Species vary widely in size from less than 2mm to about 160mm, many are massive as well as large and many males appear much larger due to exaggerated cephalic and pronotal development. Such effects include slowing beetle larvae development, reducing the size attained at adulthood and reduced breeding capacity. Dynastines are generally very distinctly coloured and patterned. treating the family as a group that includes dung beetles, chafers and dynastines but excluding other families as listed. Brindalus porcicollis (Illiger, 1803) is now extinct and Pleurophorus caesus (Creutzer, 1796), a western maritime species, is known only from old records. Pubescence is very variable; in general chafers are more pubescent then the other groups. They are small beetles, 4.5mm, elongate with the elytra covering the abdomen, and in dorsal view the labrum is visible in front of the clypeus while the eyes are concealed. Small to large species (3-20mm), most are powerfully built beetles with fossorial legs and some can swarm in large numbers. The prominent rhinoceros horn gives the beetles a menacing look. Those developing in avian and mammal nests occur throughout the world, many are generalists e.g. All species develop in decaying vegetation or dead wood and adults occur on flowers in hot weather. Therefore, the larvae hatch and are immediately surrounded by food. They feed exposed on foliage. of Onthophagus are often metallic to some extent, while chafers tend to be more gaudy, brightly coloured and metallic, tropical species more especially so, although nocturnal species e.g. Although the large brownish beetle feeds on grapevine leaves, it doesn’t cause enough damage to be classified as a pest. Spiracles cribriform, anal aperture transverse or, rarely, Y-shaped. In general the adults will die off before the next generation eclose later in the year but there are many variations on this theme and some will be explored among the species accounts. There are approximately 60 species of dung beetle in the UK. as larvae but several tribes e.g. For exa… These are 3mm shining black species with strongly punctured striate elytra and red appendages, found under bark or from the burrows of Lucanidae species.

Beetles Beetles (order Coleoptera) may be found near a cadaver in the form of adults, larvae, pupae or skin casts, with the most forensically relevant families of beetle including Staphylinidae (Rove beetles), Scarabaeidae (Scarab beetles), Carabidae (Ground beetles), Histeridae (Hister beetles), Silphidae, and Dermestidae (Hide beetles) (Kulshrestha and Satpathy, 2001). Their bodies curl into a distinctive C shape at rest. With such intense competition most species develop rapidly, produce large populations readily and disperse quickly by flight and new host material is utilized soon after its arrival. Cutting down the use of chemicals on the farm with a sustainable worm control policy that includes monitoring with faecal egg counts will help. Its other name, ‘spotted June beetle’ comes from the 4 dots on the side of its body.
