I think having stick insects is a wonderful science activity. As with any activity some of the children are very interested – watching the insects for long periods of time, eagerly anticipating the hatching and molting stages and more. Other children have little interest and rarely even notice their existence in our room.
The ‘baby’ stage is my personal favourite. They are cute when they first hatch although they can occasionally escape when they are that small;
I only keep a few of the eggs that are laid and even then when they hatch it sometimes seems like we may have too many. Sadly (luckily?) only a small percentage of the babies make it to adulthood and lay eggs for our next generation of insects.
Sometimes the little ones are hard to find when they camouflage on the sticks or on the lettuce leaf;
As they continue to grow they are easier to see but they also make more mess;
On a few occasions we have run into a problem when we have a particularly large number of insects at various stages. The adults make the cage very dirty but the numerous hatch-lings make it difficult to properly clean and keep everyone contained. If it is winter I will take the container outside briefly to clean it – cold insects are slow insects.
Last month we were at the overcrowded, filthy cage level but it wasn’t yet cold enough outside to slow them down. Then something unexpected happened. I ran out of romaine lettuce and there was NONE in the fresh produce section of the store where I was shopping. Instead of making a special trip to another store just for insect food I decided to buy a package of romaine hearts.
Back at home I tossed two leafs into the cage for the insects. The next day ALL of them were dead. A hundred + infant to adult stick insects were strewn across the bottom of the cage. I assume insecticide caused the mass extinction and I know I won’t be buying packaged romaine hearts for any reason anymore.
For the first time in six years we have no stick insects. I managed to save a few dozen eggs when I cleaned the cage but only time will tell if the insecticide affected them too. :-(
