Entomology: How Insects Eat

We have embarked on an Entomology study through 4H.

There are 4 basic ways insects can eat.

  1. chewing
  2. siphoning
  3. piercing and sucking
  4. sponging

Chewing

This way is simple.  It’s how we eat.  We move our mouth to cut and tear our food.  This is also how grasshoppers eat.

Siphoning

This is relative to sucking through a straw. Butterflies eat this way.

Piercing and Sucking

This way of eating is similar to a needle or syringe. There is a breaking of the surface and an insertion of the siphoning tube.  Mosquitos eat this way.

Sponging

This way of eating takes after its name.  It is a way of absorbing or taking in food without the use of a siphon tube or chewing.  Houseflies can only take in liquid so they often regurgitate their food.

  2. We've raised caterpillars from eggs we found in our garden. A great experience and one our entire family enjoyed. I thought you might like to see this video I took of a caterpillar chomping his way through a parsley leaf. Rather amazing! The video is in real time. ~~Rhonda :)
