On your desk you will find a box with all the supplies you need. In this box you will find eggs in which you will grow into either butterflies or ladybugs. As they grow you will need to figure out what bug you are growing. Once you know what you are growing you need to do some other research. .  . Jin, Linhai.  . Song, Wei Zhang. , . Shan.  . Lu, and .

Cind the insects and iden�fy them, either using the descript (Reduviidae) in the Order Hemiptera. Although there are many kinds of assassin bugs only a few feed on bird and mammal blood — the kissing bugs. The species most commonly encountered in California
