Common Name: Brown lacewing
Order: Neuroptera
Family: Hemerobiidae
Pest Status: This is a very beneficial insect predator and should be
protected.
Appearance: Adults are red-brown to brown-gray. The fore wings
are narrowly oval with a slightly pointed apex.
Life Cycle: Females lay their eggs singly on fir needles or between
bud scales in early spring. Eggs hatch in approximately 10 days,
depending on the temperature. When the larvae reach ¼-inch in
length, they spin a silken cocoon and pupate on the underside of a
leaf. There are one to 10 generations per year.
Where to Collect: Brown lacewings often can be found on the
bark or branches of trees, usually in forests or orchards.

Common Name: Bumble bee
Order: Hymenoptera
Family: Apidae
Pest Status: This is a very beneficial plant pollinator.
Appearance: Bumble bees are large (¾-inch to 1½-inch), hairy
bees that are generally black and yellow.
Life Cycle: The queen lays several eggs in a crevice in the middle
of the nest and then seals it with wax. Newly hatched larvae
consume part of the nest, but are also fed by the queen through
an opening in the cell wall. When the larvae are fully grown, they
spin cocoons and eventually emerge as workers that forage for the
colony and protect the nest.
Where to Collect: Bumble bees are often encountered foraging
at flowers. Wooden sheds and barns are favorite nesting place of
bumble bees, but they may nest nearly anywhere.

Common Name: Cabbage butterfly
Order: Lepidoptera
Family: Pieridae
Pest Status: Cabbage butterfly caterpillars can cause damage to
garden vegetables.
Appearance: The wings of cabbage butterflies are white-green
with black tips. There are two submarginal black spots in females,
and one in males.
Life Cycle: Adults lay eggs on the undersides of leaves, where the
larvae also feed. The butterflies overwinter as pupae and emerge in
early spring.
Where to Collect: Eggs are laid on the plants of the mustard
family (crucifers), particularly cabbage and broccoli plants. They
also are attracted to dandelions and Luminaria flowers.
