The Curious World of Yellow LadybugsLadybugs come in a variety of colors, but yellow ladybugs stand out with their bright, sunny hue These cute insects may look similar to the red ladybugs we know and love, but they have some key differences. In this article, we’ll explore the fascinating world of yellow ladybugs, including different species, what they eat, if they bite or are poisonous, spiritual meanings, getting rid of them, and more!

What Are Yellow Ladybugs?Yellow ladybugs belong to the family Coccinellidae, just like red ladybugs But most yellow ladybugs are actually a species called Asian lady beetles (Harmonia axyridis) Native to Asia, these beetles were introduced in North America and other places as a form of biological pest control.

The name “ladybug” can be misleading though, as many yellow ladybugs are not true ladybugs. Other yellow insects simply resemble ladybugs, like the squash lady beetle and fungus-eating ladybird. Still, they are colloquially referred to as “yellow ladybugs.”

Why Are Some Ladybugs Yellow?Ladybugs come in different colors like red orange yellow, and black. Their coloring is tied to their habitat and functions as camouflage. Yellow ladybugs blend in well with the faint yellows of flowers and plants. The bright color also warns predators that the ladybug may have a foul taste.

Additionally, yellow ladybugs signal to other insects that they are toxic or unpalatable. This is called aposematic coloration. So even though yellow may stand out to our eyes, it serves an important evolutionary purpose for ladybugs.

Common Yellow Ladybug Species
There are over 5,000 species of ladybugs in the world. Here are some of the most common yellow ladybugs:

• Asian lady beetle – An invasive species introduced for pest control. Yellow with variable black spots.

• Fourteen-spotted lady beetle – Yellow with 14 rectangular black spots. Introduced to control aphids.

• Squash lady beetle – Bright yellow with black spots. Feeds on squash plants.

• Fungus-eating ladybird – Entirely yellow with black markings. Eats fungus on leaves.

• 22-spot ladybug – Yellow with distinct 22 round black spots. Eats mildew.

• Variegated fungus-eating lady beetle – Yellow and black coloration. Eats fungus.

As you can see, yellow ladybugs encompass a diverse group. Some are native, while others are invasive. They also occupy different ecological niches based on their diet.

What Do Yellow Ladybugs Eat?
The food source of yellow ladybugs depends on the species. Some are predacious and eat other insects like aphids. Others are fungivores and eat fungus, mildew, and plant debris.

Aphids
Certain ladybugs like the Asian lady beetle and fourteen-spotted lady beetle thrive on aphids. Aphids damage crops by sucking out plant juices. So farmers welcome these aphid-eating yellow bugs.

Mildew
Some yellow ladybugs feast on powdery mildew. This fungus contaminates cucurbits like cucumbers, squash, and melons. Yellow ladybugs provide natural pest control by clearing away the mildew.

Plants
A minority of yellow ladybugs are phytophagous, meaning they eat plants directly. For example, the squash lady beetle consumes squash flowers and leaves. This makes them a nuisance for gardeners growing squash.

As you can see, most yellow ladybugs are beneficial thanks to their diet of other insects and fungi. But certain species are unwelcome guests in gardens because they damage plants.

• The pinch feels comparable to a slight static shock.

Of course, yellow ladybugs will bite if severely threatened. And some people may experience minor irritation from a pinch. But in general, these happy colored bugs are harmless!
