    I thought I had army worms on my pine trees, but these guys are dark grey/green with shiny black head. They do have a full dorsal stripe in light grey and side stripes in darker grey. When disturbed they rear up to show six black front legs while the rest of the legs are light green or greyish suction pads. They team up two to a needle and consume. You can find them in a mass of maybe 30 at a time. I know it’s not crop but we are farmers and would like to know what we’ve got.

    Thanks Tracey, that is exactly what they are.

    Hi Tracey,
    I came across a patch of wheat that had a percentage of dried up heads in the mix(10-20%). Upon further investigation the whole stalk had been completely clipped at or just above ground level. The patch wasn’t overly large and was probably 40 ft off the field edge. There was minimal evidence of leaf feeding. It was dusk and I wasn’t carrying my flashlight so as to get a better look. What do you suppose caused this? The field is located at the corner of Kent Line and Mawlam.
    Thanks,
    Mark
