31 May 2016

“Green Ladybugs” honeybees and butterflies feast on thistle nectar high in the Great Smoky Mountains. These pretty green ladybugs, are not really ladybugs at all, but Spotted Cucumber Beetles! They are native and non-invasive and normally live quiet lives in the forests and meadows doing little damage, but when they invade backyard gardens and farms they become a serious agricultural pest. There really are no greenish ladybugs – ladybugs are more “rounded” and have very short antennae compared to the cucumber beetles.

Herbivore dung as food for dung beetles: elementary coprology for entomologists

PETER HOLTER

Article first published online: 22 APRIL 2016

1. How do dung beetles and their larvae manage to subsist on herbivore dung consisting of plant remains that are at least partly indigestible, mixed with various metabolic waste products? To clarify what is known and not known about this basic aspect of dung beetle biology, the present review summarises information on dung composition and discusses the feeding of beetles (food: fresh dung) and larvae (food: older dung) in relation to this information.

2. There is 70–85% water in typical fresh dung, and undigested lignocellulose or ‘fibre’ constitutes about 70% of the organic matter which also contains 1.5–3% N. About 75% of this is ‘metabolic faecal nitrogen’, mostly associated with dead and alive microbial biomass. As all essential amino acids and cholesterol are probably present, additional synthesis by microbial symbionts may not be needed by the beetles.

3. Beetles minimise the intake of lignocellulose by filtering fibre particles out of their food which is probably microbial biomass/debris with much smaller particle size. Excess fluid may be squeezed out of this material by the mandibles before ingestion.

4. All larvae are bulk feeders and unable to filtrate, but little is known about the composition of their food, i.e. older dung in pats or underground brood masses. Larvae in dung pats may depend on easily digestible dung components, probably microbial biomass, whereas the nutritional ecology of larvae in brood masses is still not understood. Unravelling the composition of their food might answer some of the so far unanswered questions.

Ladybirds mating, video


This 5 April 2016 video shows two ladybugs mating. The mating may last for 45 minutes. In the Netherlands, female ladybirds lay eggs in May. Alex Molin from the Netherlands made the video.
