Pollinators receive food in the form of nectar (source of sugar) or pollen (source of protein, fat, and other nutrients). In the process of moving from flower to flower to feed, pollinators disperse pollen grains among plants of the same species, enabling the plants to reproduce. Flowers have evolved over long periods of time into many colors, shapes and scents to attract their pollinators, thus creating a mutually beneficial relationship.
The Pollinators
While bees are the primary pollinators, other insects including butterflies, moths, flies, beetles, wasps, some birds such as hummingbirds, and bats also play important roles.
Honeybees & Native Bees
Honeybees (genus Apis) are the bees we are most familiar with. However, honeybees are just one species of a very diverse group with over 20,000 species worldwide, 4,000 species in the USA and 1,600 in California. Native bees come in a variety of shapes, colors, sizes and lifestyles that make them very efficient pollinators. Unlike honeybees and bumblebees, which are social bees living in colonies, native bees are solitary with 70 percent nesting in the ground with the rest nesting in wood and plant stems.
Butterflies
Butterflies are daytime flying insects who often have gorgeous colorful wings. Their larvae sometimes require a specific plant to feed on, though most adults will get their nectar from many plants.
Moths
Moths are mostly evening and nighttime fliers, though some are out in the late afternoon or early morning. They are attracted to sweet-smelling flowers. Less colorful than butterflies, they are easily differentiated from butterflies by their “feathery” antennae.
Flies
Flies are not generally thought of as pollinators, however many are, particularly hover flies (family Syrphidae) and bee flies (family Bombyliidae), both of which are generalist pollinators. Generalist pollinators visit a wide range of plants, making them important inhabitants of gardens and fields.
Beetles
Beetles are a large group, with up to 28,000 species in the USA. Most beetles are not pollinators, but some do visit flowers for nectar or pollen and help fertilize some flowering plants, particularly magnolias.
Wasps
Hummingbirds
Hummingbirds are the most prominent pollinating birds in the Americas. With their long beaks, they can reach deep into flowers while sipping nectar. In addition to nectar, they also forage on insects and spiders.
Bats
Bats are nocturnal pollinators that play an important role in pollinating cacti and agave, as well as many tropical and subtropical plants including bananas, avocados, century plants and cashews. Species such as Mexican long-nose bat (Leptonycteris nivalis) have evolved heads and long tongues to access light-colored flowers which open at night, often producing abundant nectar and pollen.
How You Can Help Pollinators
Pollinators need a diversity of flowers with lots of nectar and pollen. They require easy access to flowers blooming throughout the seasons, particularly during late winter, early spring, and late autumn seasons when fewer flowers bloom. Different flower species provide differing amounts of nectar. Native plants generally provide more nutritious nectar for pollinators, so they attract more pollinators. Download the Xerces Society Recommended Plants for the Central Valley Region for a list of plants.
To help protect pollinators, if you choose to use a pesticide, select one that are less toxic, such as an insecticidal soap or oil. Avoid broad-spectrum sprays that kill numerous insects. Spray on non-windy days in the early morning or late evening when pollinators are not present. Use UC Integrated Pest Management for information on pests and pest management (https://ipm.ucanr.edu/).

What do pumpkins need?
Space - Pumpkin plant vines can grow over 20 feet long. Give plants plenty of space to grow. Use a tomato cage or small trellis for mini pumpkin varieties. For larger pumpkins, vines can grow on a fence. Make sure to support each pumpkin with a “sling” like a t-shirt or tied nylon stocking tied that is also tied to the fence.
Mounds - Make a small mound or hill and plant 3-5 pumpkin seeds per hill. Create a small basin around each planting to help keep the soil moist until seedlings appear.
Water – Water early in the morning. As the plants mature, water deeply and infrequently to a depth of 12 inches, allowing the soil to dry out slightly between watering.
Fertilizer – If desired, you can use a vegetable fertilizer labeled for pumpkins.
Thinning – If growing large pumpkins, select the best-looking fruit when it is small, and remove the others. This will send all the nutrients into that pumpkin so it can grow large.
Possible Pests
If you see any of these pests on your plants, visit the UC IPM Website tips on what to do.
Just for Fun
When pumpkins are small, carve your name or a cool design on the skin and it will become more apparent and look extra spooky as the pumpkin gets larger.

/h3>/h3>/h3>/h3>The UC Cooperative Extension Master Gardeners are giving Vermicomposting Classes in June that will be fun for the WHOLE family!
Vermicomposting is the process of using red wiggler worms* to help eat kitchen scraps. Join us for this class to learn interesting facts about these worms, how to make your own “worm hotel,” and which foods the red wiggler worms eat that can help turn your kitchen scraps into compost for your garden!
In addition to presenting information about vermicomposting, you'll be able to “meet” a few live worms and see them in action in a worm bin. Kids of all ages will love "meeting" the worms, so be sure to bring them. We hope you can attend at one of these local Stanislaus County Library locations:
*earthworms don't like to be disturbed, so they are not used for vermicomposting.
