“after entering the third instar ... the larvae confine<br />

their feeding to the roots <strong>of</strong> <strong>grass</strong>es” (Carne &<br />

Chinnick 1957 p. 608); “prefer <strong>grass</strong>es over broadleaf<br />

plants” (Allsopp & Hitchcock 1987 p. 20);<br />

“feed upon young roots” (Britton 1987 p.687).<br />

“larvae preferentially select and feed on living<br />

roots” (Ridsdill-Smith 1975 p. 75); “feed upon<br />

young roots <strong>of</strong> <strong>grass</strong>es” (Britton 1987 p.687)<br />

larvae damage seed and seedlings before<br />

emergence, adults usually eat the seedling at<br />

ground level; Pterohelaeus are “major root and<br />

seedling pests”, Isopteron “recorded feeding on<br />

geminating wheat” (Matthews & Bouchard 2008)<br />

“failure <strong>of</strong> seedling development” (Hely 1958 p.<br />

& McAlpine); may similarly effect other <strong>grass</strong>es in<br />

submerged situations<br />

inside young growth; may be largely bacteriafeeders<br />
