They are called weevils are very common in wheat and grain, which is what pasta is made from. We live in Florida and keep our house on the cooler side since heat and humidity can cause the eggs to hatch. We also keep flour, sugar and corn meal in the fridge for that reason. Learned that from my granny. They won't hurt you, though I can see why it would freak you out the first time you see them. However, you have eaten them a million times if you have eaten any type of pasta before. You just did not see them.
