Blueberry – Yellownecked Caterpillars (small sized)

Q:I just found these on one leaf of my highbush blueberry bush. Are they the start if those horrible yellow neck caterpillars?

A:Your suspicions are correct – they are immature yellow necked caterpillars, probably Dantana ministra.

If you allow them to develop into adults they will consume many leaves.

Fortunately, a quick spray with a product that contains Bacillus thuringiensis (B.t.) click for sources) will easily control them.
