Academic Reading sample task – Diagram label completion

[Note: This is an extract from an Academic Reading passage on the subject of dung

beetles. The text preceding this extract gave some background facts about dung

beetles, and went on to describe a decision to introduce non-native varieties to

Australia.]

Introducing dung1

beetles into a pasture is a simple process: approximately 1,500 beetles

are released, a handful at a time, into fresh cow pats2

in the cow pasture. The beetles

immediately disappear beneath the pats digging and tunnelling and, if they successfully

adapt to their new environment, soon become a permanent, self-sustaining part of the

local ecology. In time they multiply and within three or four years the benefits to the

pasture are obvious.

Dung beetles work from the inside of the pat so they are sheltered from predators such

as birds and foxes. Most species burrow into the soil and bury dung in tunnels directly

underneath the pats, which are hollowed out from within. Some large species originating

from France excavate tunnels to a depth of approximately 30 cm below the dung pat.

These beetles make sausage-shaped brood chambers along the tunnels. The shallowest

tunnels belong to a much smaller Spanish species that buries dung in chambers that hang

like fruit from the branches of a pear tree. South African beetles dig narrow tunnels of

approximately 20 cm below the surface of the pat. Some surface-dwelling beetles,

including a South African species, cut perfectly-shaped balls from the pat, which are

rolled away and attached to the bases of plants.

For maximum dung burial in spring, summer and autumn, farmers require a variety of

species with overlapping periods of activity. In the cooler environments of the state of

Victoria, the large French species (2.5 cms long), is matched with smaller (half this size),

temperate-climate Spanish species. The former are slow to recover from the winter cold

and produce only one or two generations of offspring from late spring until autumn. The

latter, which multiply rapidly in early spring, produce two to five generations annually.

The South African ball-rolling species, being a sub-tropical beetle, prefers the climate of

northern and coastal New South Wales where it commonly works with the South African

tunneling species. In warmer climates, many species are active for longer periods of the

year.
