Top 20 Most Common Insects in Half Moon Bay

Bombus melanopygus is a non-woven insect from the family of bees and bumblebees (Apidae). The scientific name of the species was first validly published in 1848 by Nylander.

The convergent lady beetle (Hippodamia convergens) is one of the most common lady beetles in North America, which is a great thing given that it is a common biological control agent of aphids. They lay a good chunk of eggs over a couple of months. If you have ever seen a small, black alligator-like insect, you may have seen one of its larva.

Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.

The fiery skipper (Hylephila phyleus) is a butterfly of the family Hesperiidae and is approximately 1 inch (2.5 cm) long. The males are orange or yellow with black spots while the females are dark brown with orange or yellow spots. The caterpillars are greenish pink with a black head. The caterpillars are often considered pests and can feed on Bermudagrass, creeping bentgrass, and St. Augustine grass. Fiery skippers, along with all other species of skippers and skipperlings, can hold their wings in a "triangle" shape. The forewings are held upright, and the hindwings are folded flat. This position is thought to better absorb the sun's rays. The fiery skipper lives in North and South America, from Canada to Argentina. It is a migratory species.

The yellow-faced bumble bee (Bombus vosnesenskii) is known for its mostly black body with a yellow face. Their population is not dropping, but continued expansion of urban human populations is causing some difficulty for this bee to make nests. But what it does find it tends to monopolize due to its early arrival in the season.

The california Gall Wasp ( Andricus quercuscalifornicus ), is known for its ability to induce galls on oak tree stems. The galls form a persistent shelter for various kinds of fungi as well as many other insects. If it wasn’t for the reproduction, they would stay in the galls forever.

It is a large, brightly colored and active butterfly, rarely seen at rest; its wingspan is 8 - 10 cm, and its wings are yellow with black stripes, and it has blue and orange spots near its tail. It has the "tails" on the hindwings that are often found in swallowtails. The eggs are deep green, shiny, and spherical. Young caterpillars resemble bird droppings, and as they molt, they eventually turn bright green, with a pair of large yellow eyespots with black and blue pupils. The caterpillars molt five times, eventually reaching a length up to 5 cm before pupating.

Strymon melinus is a butterfly of the family Blüullingen (Lycaenidae) of the subfamily of Hairstreak (Theclinae).

The western yellowjacket (Vespula pensylvanica) is known for its painful stings. It often flies near areas with crowds of people and lots of food. These wasps will aggressively guard their nests, which is how many people get stung. Their round, paper-like nests are usually built on the ground, where they should be avoided at all costs.
