Bugs in the Brook


Are you curious about Insects?  Calling all future entomologists (those who are interested in  bugs), entering grades 3-6.  

On Friday, June 23rd, from 10:00 AM-12:00, join Carolyn Rubinfeld, PV water ambassador, at the Thielke Arboretum, to explore the macro invertebrates (bugs) that live in Diamond Brook.   

Carolyn will guide participants in collecting, identifying, and comparing/contrasting these finds to other bugs drawn from a pristine stream in Morris County.  Primary points will include the impact of fertilizer runoff, sedimentation build up, and poor quality oxygen supply in Diamond Brook.  

This is a hands-on highly supervised outdoor workshop, rain or shine.  Wear boots, bring drinking water, and don't forget sunscreen and a hat.


This is a very personalized fun experience,  limited to twelve (12) participants. Learn from an expert!  Early registration is recommended. 

Registration is online only, click here.  

Cost is $10 for members, and $15 for non-members.
