Caterpillars Count! Join new citizen science project

Caterpillars Count! is a citizen science project sponsored by the National Science Foundation for measuring the seasonal variation and abundance of arthropods like caterpillars, beetles, and spiders found on the foliage of trees and shrubs. Arthropods are an important food source for birds and other wildlife.

Climate change is affecting the timing of spring leaf out, insect activity, and bird migration and breeding. But are the plants, insects and birds all responding to the same degree? If either insects or birds are not keeping up with the shifts of the other organisms that they depend on, then further climate change may have negative consequences for their populations.

Caterpillars Count is part of a multi-university study of phenological mismatch across three trophic levels in eastern North America. The lead universities are University of North Carolina, Georgetown University, and University of Connecticut, with co-investigators from University of Florida, Institute for Bird Populations, Penn State, Evergreen State College, and Ontario Forest Research Institute.

Participants will monitor a site at the Walker Nature Center in Reston for Georgetown University. We will examine 50 leaves on each of 10 trees weeklyor bi-weekly thoughout the spring and summer.  We will count and classify the arthropods we observe. Each monitoring session will take about one hour. There will be approximately 16 monitoring sessions. Volunteeers are not required to participate in every session and the timing is up to the volunteers who are participating. Volunteers must sign-up in advance for training and schedule coordination.

This project is eligible for credit for master naturalists under code C-254.

Attend Butterfly Identification Workshop, with Dr. Leslie Ries, 25 June

The sight of butterflies fluttering around on a warm day is one of the most iconic signs of summer. These beautiful insects usually only live for a few weeks as adults, but they make quite an impression while they are in their full glory. There is a large variety of butterfly species in our area and we are going to census them on June 30 during the Audubon Society of Northern Virginia Butterfly Count in and around our Occoquan Bay Count Ciricle.  

In preparation, Dr. Leslie Ries will be teaching a butterfly workshop focusing on identifying butterflies in Northern Virginia. The classroom portion of the workshop is FREE and will be on Monday, 25 June.

The field trip portion will be in conjunction with the count on June 30.

Your field guide to battle ticks in Fairfax County

Tick-tock… According to mother nature’s clock, it is tick season again, which means it is time to start thinking about protection and prevention.

Ticks are a concern every spring and summer because they can transmit infections that can cause people to become sick. Lyme disease is still the best known and most common disease spread by ticks in Virginia, but there are others such as Rocky Mountain spotted fever and ehrlichiosis.

Factors like weather, habitat and the availability of host animals can affect the tick population from year-to-year and make it hard to predict their numbers. “What we do know is that ticks are found throughout our area, so it’s important to take steps to prevent tick bites when you are working or playing outdoors,” says Josh Smith, an environmental health supervisor with the Health Department.

There are three tick species regularly found in Fairfax County that can transmit disease to humans:

Black-legged or Deer Tick (Ixodes scapularis)
Lone Star Tick (Amblyomma americanum)
American Dog Tick (Dermacentor variabilis)
