Mordellistenula perrisi

**Mordellistenula perrisi**

**Definition**
*Mordellistenula perrisi* is a species of beetle belonging to the family Mordellidae, commonly known as tumbling flower beetles. It is characterized by its distinctive body shape and behavior, typical of the Mordellidae family.

## Overview

*Mordellistenula perrisi* is a member of the order Coleoptera, which encompasses all beetle species. Within this order, it is classified under the family Mordellidae, a group known for their wedge-shaped bodies and unique tumbling motion when disturbed. The species was first described in the 19th century and has since been recognized for its ecological role in various habitats, particularly in relation to flowering plants.

## Taxonomy and Classification

– **Kingdom:** Animalia
– **Phylum:** Arthropoda
– **Class:** Insecta
– **Order:** Coleoptera
– **Suborder:** Polyphaga
– **Family:** Mordellidae
– **Subfamily:** Mordellinae
– **Tribe:** Mordellistenini
– **Genus:** Mordellistenula
– **Species:** *Mordellistenula perrisi*

The genus *Mordellistenula* is one of several within the Mordellidae family, distinguished by subtle morphological traits such as body size, shape, and antennal structure. The species epithet *perrisi* honors the entomologist who either discovered or first described the species.

## Morphology

### General Appearance

*Mordellistenula perrisi* exhibits the characteristic body form of tumbling flower beetles: an elongated, wedge-shaped body tapering to a pointed abdomen. The beetle’s exoskeleton is typically hard and may display a range of colors from dark brown to black, sometimes with lighter markings depending on the specimen and environmental factors.

### Size

Individuals of *M. perrisi* are generally small, with body lengths ranging from approximately 3 to 6 millimeters. This size range is consistent with many Mordellidae species, which are often overlooked due to their diminutive stature.

### Distinctive Features

– **Head:** The head is usually small relative to the body, with compound eyes that provide a wide field of vision.
– **Antennae:** The antennae are filiform (thread-like) or slightly serrate, aiding in sensory perception.
– **Legs:** The hind legs are well-developed and adapted for jumping, a behavior that complements their tumbling escape mechanism.
– **Elytra:** The hardened forewings (elytra) cover the abdomen but often leave the last few abdominal segments exposed, a trait common in Mordellidae.

## Behavior and Ecology

### Tumbling Motion

One of the most notable behaviors of *Mordellistenula perrisi* and its relatives is their tumbling motion. When disturbed, these beetles leap and tumble erratically, which serves as an effective defense mechanism against predators.

### Habitat

*M. perrisi* is typically found in environments rich in flowering plants, such as meadows, forest edges, and gardens. The species is often associated with flowers, where adults feed on pollen and nectar.

### Feeding

Adults primarily consume pollen and nectar, playing a role in pollination, although they are not considered major pollinators. Larvae of Mordellidae species, including *M. perrisi*, generally develop in decaying wood or plant stems, feeding on decomposing organic matter.

### Life Cycle

The life cycle of *Mordellistenula perrisi* follows the typical beetle development stages: egg, larva, pupa, and adult. Larvae develop within plant material, which provides both food and protection. After pupation, adults emerge to continue the reproductive cycle.

## Distribution

*Mordellistenula perrisi* is primarily distributed in parts of Europe, with confirmed sightings in countries where temperate climates support its preferred habitats. The exact range may vary, but the species tends to inhabit regions where flowering plants are abundant.

## Importance

### Ecological Role

As a pollen and nectar feeder, *M. perrisi* contributes to the pollination of various plant species, albeit to a limited extent compared to specialized pollinators. Its larvae aid in the decomposition process by breaking down dead plant material, thus contributing to nutrient cycling in ecosystems.

### Scientific Significance

The species is of interest to entomologists studying the diversity and behavior of Mordellidae beetles. Its distinctive morphology and behavior provide insights into evolutionary adaptations among beetles.

## Conservation Status

Currently, there is no specific conservation status assigned to *Mordellistenula perrisi*. The species does not appear on major endangered species lists, suggesting it maintains stable populations within its natural range. However, habitat loss and environmental changes could potentially impact local populations.

## Research and Study

Research on *Mordellistenula perrisi* is primarily taxonomic and ecological, focusing on its classification, distribution, and role within ecosystems. Further studies could explore its interactions with plant species and responses to environmental pressures.

**Meta Description:**
*Mordellistenula perrisi* is a species of tumbling flower beetle known for its distinctive body shape and behavior. It inhabits flowering plant-rich environments and contributes to pollination and decomposition processes.
