These guys love to eat aphids (see bad bugs below).
Ladybug larva wiki.jpg
Ladybug Larva

They can look kind of creepy when
they're in their young larva form.

That bright red color on the adults helps to keep birds from eating them.
Bees & Bumble Bees
A gardener's best friend. Bees spread pollen from plant to plant.
Pollen fertilizes the flowers, so the veggies can grow.
Praying Mantis
These bugs will eat aphids. They'll also eat anything else they can
get their hands on!

Some don't consider them good bugs at all.
They're not something you'd welcome to your butterfly garden!
Green Lacewing
You'll see these delicate insects flying around mostly at night.
Green Lacewing Larva

When they are young, they're mighty
hunters, eating aphids, mites, leafhoppers and other garden pests.
Hoverfly Wiki.jpg
They might look like bees or wasps, but they're flies without stingers.
Like bees, they feed on nectar and pollen and help plants to
Hoverfly Larva

When they are young (in larva form) they are called aphid lions!
Look at this little guy on the right munch down on an aphid!

Aphids wiki.jpg
Aphids like the tender new growth of plants, where they attach themselves
to suck out the liquid sap from the plants. They exude a sticky honeydew
that ants like to harvest. Follow an ant trail up a plant to find the aphids.
They come in many colors -- grey, black, green, orange, even pink!

Control Approaches
- Knock off aphids with a forceful spray from a hose.
Aphids can't crawl back up.
- Release lady bugs to eat them.
- Use an organic product like Safer's insect killing soap or Gardner &
Bloom insect control sprays
Common Garden Snail.jpg
Snails & slugs
Snails and slugs like to eat what we grow.

Control Approaches
- Use an organic product like Sluggo Plus.
- Place a wooden board on the ground & collect them in the morning.
Cutworm damage.jpg
The enemy of vegetable seedlings. These are not
worms at all, they are actually moth caterpillars. They live in the
ground and they love to come out at night and lop the stems off
young plants.

Control Approaches
- Use an organic product like Sluggo Plus.
- Put a collar around young plants (like a cardboard tube), that
cutworms can't climb up.
Harlequin Beetle.jpg
Bagrada or Painted Bug
Pretty, but destructive. These are easily mistaken for Harlequin Beetles.
Like Harlequins, you often find them in pairs, attached by their ends.
They suck the sap from plants and make the leaves look scorched or
wilted. These bugs have only been in CA for a few years, but have caused
lots of damage.

Control Approaches
- Hand-pick.
- Look for their clutches of eggs on the undersides of leaves.
