Hi Emily, That black insect is not a leaf eating beetle, it is a bug that sucks sap: in this case, it is probably harmless. Maverick should have controlled any leaf eating caterpillars. These insects were nibbling away at your tiny leaf buds. Maybe you didn’t notice this, only noticing when the leaves opened up to show the damage. My inclination is to do nothing for now, but carefully look for a subtle mess of webbing on any more new growth. If you find it, spray with Maverick. Healthy Pendas repel caterpillars, so yours are probably unhealthy. Look out for bad signs around your plants. Maybe the clay soil is compacted and water is not penetrating the ground – if so, try to fork over the soil.
