This video says about itself:
Nighttime infrared video footage of the dung beetle Deltochilum valgum attacking a millipede in the Peruvian rainforest. Ecologically distinct from its co-occurring dung-feeding relatives, this species is a specialized predator of millipedes and the first case of an obligate predatory dung beetle. The beetle kills the millipede by prying apart its segments, often through decapitation, before feeding on its soft inner tissues.

Beetles found after going missing for more than 100 years
April 2009. An amazing seven species of beetle have been found at the National Trust’s Dunham Park in Cheshire after last being recorded there more than 100 years ago.
John Hooson, National Trust Nature Conservation Adviser, said: “Dunham is one of the most studied parklands in the UK, making this a very special discovery. These beetles are small and finding so many that haven’t been seen since Queen Victoria was on the throne is remarkable and confirms that this is a special place for wildlife.”
Two of the major rediscoveries from the survey were the rare flat bark beetle Pediacus depressus, last recorded here in 1889, and normally found south of the line between the river Severn and the Wash, and the nationally scarce false darkling beetle Abdera quadrifasciata which was last reported at Dunham in 1867 and is at the northern limit of its range. There were also two new discoveries for the site from the survey – the nationally scarce darkling beetle Pseudocistela ceramboides, the furthest north it’s ever been found, and the nationally scarce hister beetle Aeletes atomarius, which hadn’t previously been recorded in the north-west of England.
Top site for veteran trees
Dunham Park is one of the top sites in the UK for veteran trees – an old tree that has had time to develop a variety of features such as fungi and sap runs – such as oak and beech which have survived in the park for many centuries.
The long continuity of such veteran trees has made the park an ideal location for wood-decay beetles. Results from this latest survey of the parkland, by expert zoologist Dr Keith Alexander, have confirmed that the park is the fifth richest site for such specialist beetles in the British Isles, supporting national and international rarities.
Renowned beetle habitat
Famed for its diverse variety of wood-decay beetles, searching for them at Dunham Park became popular in the 1860s and the site has been visited by countless experts ever since. Local entomologist Joseph Chappell was the first person who published notes on the rarities found in the parkland.
