Milkweed bug eating its young?

I saw a large milkweed bug adult that appeared to be eating a large milkweed bug nymph today. It had straddled the nymph, inserted its proboscis into its abdomen and, over the course of an hour, drained it and killed it. The nymph attempted to run away a few times and they were both on a fresh milkweed pod.

Is there any reason why the adult would feed on the nymph instead of the milkweed pod that was right there? Or just in general, why an herbivorous insect would eat another insect when there was abundant food?

I have several photos but I'm not sure how to upload them in the forums (if that's even an option).

Thanks for any replies!

No, don't upload photos to Forums
