Insect Identification on Plum Bush #873001

Asked June 13, 2024, 3:40 PM EDT

Our Plum Bushes have aphids we have treated with soapy water and several days later with ladybugs. That seems to be helping but there are also a yellow insect on several leaves and some bark. What are these and are they perhaps laying the aphid eggs? See attached photos.

Hi Tom,

Those are just the pupae of the ladybugs.
