Mordellistena dolobrata facts for kids

Mordellistena dolobrata is a type of beetle. It belongs to a group of beetles called Mordellistena, which are part of the larger Mordellidae family. This specific beetle was first described in 1873 by a scientist named Theodor Franz Wilhelm Kirsch.

What is a Tumbling Flower Beetle?

Mordellistena dolobrata is often called a "tumbling flower beetle." This name comes from how they move. When they feel threatened, these beetles can tumble and jump around very quickly. They are usually found on flowers, where they feed on pollen and nectar.

Where Do They Live?

Tumbling flower beetles, including Mordellistena dolobrata, are found in many parts of the world. They prefer places where there are lots of flowers, as these are their main food source. You might find them in meadows, gardens, or forests. They are active during the day, especially when the sun is out.

What Do They Look Like?

These beetles are generally small and have a unique shape.

Size and Shape

Most tumbling flower beetles are quite tiny, usually only a few millimeters long. They have a distinctive body shape that looks a bit like a wedge. Their head is often tucked under their body, and their back end (abdomen) tapers to a point. This pointed abdomen helps them move around quickly.

Colors and Markings

Their colors can vary, but many are dark, like black or brown. Some might have patterns or lighter markings on their bodies. Their outer wings, called elytra, are often smooth and shiny.

What Do They Eat?

Adult Mordellistena beetles mainly eat pollen and nectar from flowers. This makes them important pollinators, helping plants reproduce. The larvae (young beetles) of these species often live inside plant stems or decaying wood. They feed on the plant material or fungi found there.

Life Cycle of a Beetle

Like all beetles, Mordellistena dolobrata goes through a complete metamorphosis. This means they have four main stages in their life: egg, larva, pupa, and adult.

Eggs and Larvae

The female beetle lays her tiny eggs on or near plants. Once the eggs hatch, small worm-like creatures called larvae emerge. These larvae spend their time growing and eating. They usually live hidden inside plant stems or wood, safe from predators.

Pupae and Adults

After the larva has grown enough, it changes into a pupa. This is a resting stage where the larva transforms into an adult beetle. Inside the pupa, the beetle's body completely reorganizes. Finally, the adult beetle emerges from the pupa. The adult then flies off to find food and a mate, starting the cycle all over again.

Why Are They Important?

Even though they are small, tumbling flower beetles play a role in nature. As adults, they help pollinate flowers, which is vital for many plants to produce seeds and fruits. Their larvae also help break down plant material, contributing to the health of ecosystems.
