Schools require (and grade) science projects in a lot of different ways.

I have twin sons and have a hard time coming up with new or different science projects each year. One of them has decided to use their bug collections but we cant think of what would be a good topic in using the various bugs in their collections. They each have various large butterflies, moths, beetles, locusts, dragonflys, bees and preying mantis’. Can you help?

It isn’t really a useful thing to know in terms of taxonomy or physiology, so that makes sense. There are a lot of keys that have characters like “eyes touching midline of head”, but that isn’t a percentage.

Scientists seem to have studied the way in which the eyes are arranged, or how many facets they have and how big they are, but not to quantify the volume of a head/volume of eyes.

Many insect larvae don’t have very big eyes–wasp larvae would be one example.

To accurately give you a percentage, I’d need to know the volume of the insects’ heads–which I don’t know off the top of my head.

And it’s a holiday weekend, so I may wait a while until I calculate that

However, I’m not aware of any studies that can answer your distance question.

And if I go over your head, please tell me!
Part of the purpose of my blog is for me to try to practice writing without using science jargon.

Scientists sometimes speak a different language, which I think is part of reason science is so poorly understood by the general public.
