Yesterday I went out to my garden and found what looked to me to be seeds, somewhat like millet, on my tomato plant. Upon further inspection it was clear that the “seeds” had little spindly and transparent legs. Searching those characteristics online really didn’t help. I image searched “tan round garden pest” and it wasn’t until an image of normal looking aphids came up that I noticed my culprit. Apparently what I saw in the garden were aphids that had been “mummified” by the Aphelinid Wasp. The parasitic wasp lays its egg inside an unknowing aphid and when it hatches, the larvae eats the aphid out from the inside. Crazy.
