Meganoton analis (Ezo-shimofuri-suzume)

Introduction

Ezo-shimofuri-suzume is a large hawkmoth belonging to the family Sphingidae.
Because there is no widely standardized English common name in regular use, this article uses the Japanese name in romanized form together with the scientific name.

It has been recorded in multiple regions of Japan and is known as one of the larger gray-patterned hawkmoths encountered at night.

Appearance

Adults are robust and heavy-bodied, with gray to gray-brown forewings marked by dark streaks and bands.
The overall pattern often appears mottled and bark-like, helping the moth blend into woody surfaces when at rest.

Habitat & Distribution

This species is associated with wooded habitats.
It may be encountered wherever suitable habitat and larval host plants are present.

Behavior

Adults are primarily nocturnal and may come to artificial lights at night, making them possible to observe around outdoor lamps or during light-trapping.
Seasonality can vary by region and yearly conditions, but observations are generally concentrated in the warmer months.

Diet

Larval host plants have been reported for this species, but because host records can vary by locality, this article avoids listing specific plant species unless confirmed by reliable regional references.

Reproduction

Adults mate and females lay eggs on suitable host plants.
Larvae develop by feeding on host plant leaves before pupating and later emerging as adults.

Conservation

Conservation status can differ by region and depends strongly on habitat quality and local environmental conditions.
Maintaining healthy woodland habitats is important for supporting stable moth populations.

Author’s Impression

This species leaves a strong impression due to its size and solid, bark-like coloration.
Rather than being flashy, it blends quietly into its surroundings, making encounters at lights especially satisfying for moth enthusiasts.
