There are a few possibilities when you find black bugs on squash plants: 

  • Pickleworm Pupa
  • Black Aphids
  • Squash Bugs

Read on for more details about these bugs and how to prevent/ treat them.

#1. Pickleworm Pupa

You might come across some black bugs on your squash plants that seem a bit confusing, like these are pickleworm pupae. They’re the next stage after pickleworm caterpillars, like squash-eating caterpillars. As these caterpillars grow up, they become pupae, like a stage where they’re getting ready to become adult insects. These pupae might not directly hurt your plants, but they show that there could be more pickle worms around, and those can damage your squash. To handle this, you can use methods like covering your plants with cloth, using the proper sprays, and ensuring your garden is clean and healthy. This way, you can stop the pickle worms from causing too much trouble for your squash plants.

#2. Black Aphids

Black aphids can be a worrisome sight on your plants. These tiny, soft-bodied insects are a garden pest that feeds on plant sap. They gather in groups on plant stems and leaves, extracting sap and weakening the plants through feeding, causing damage. The black coloration of these aphids is due to a protective coating they produce, often making them appear as tiny black dots on leaves. While they might not be as common as other aphid types, their presence can still impact plant health and growth.
