Aphid under a microscope at 40X magnification.🪲🔬Aphids are small soft-bodied sap sucking insects that feed on plant juices. Seedlings are vulnerable to aphids as they are usually high in nitrogen, which aphids are attracted to. Amending your garden with organic compost or worm castings will provide a slow-release form of nitrogen. Keeping plants healthy will prevent plant stress. Plants that are unhealthy or stressed release hormones that may attract insect pests. More info in comments. ⬇️🌱💚
