Early spring to fall


Meadows, fields, gardens, houses. Any place having plants with aphids.


3 16 to 5 16



This is a 3 16 to 5 16 long ladybird beetle.

The body is oval and dome-shaped. The transition between the head and thorax plate (pronotum), and between the pronotum and the forewings (elytra) is smooth.

The pronotum is white with 4 black spots or patches that may blend together into a W or M pattern, depending if it is viewed from the front or from behind. This is the only reliable identifying feature in the field.

The thick, hardened, shell-like forewings (elytra) are highly variable. They may be orange with black spots, orange with no spots, or red with black spots. Fully spotted individuals have 10 black spots on each wing cover.

The legs are usually brown or reddish.


Multicolored Asian lady beetle (Harmonia axyridis f. conspicua) elytra are black with two red spots.

Multicolored Asian lady beetle (Harmonia axyridis f. spectabilis) elytra are black with four red spots.

Seven-spotted lady beetle (Coccinella septempunctata) elytra are spotted in a 1-4-2 pattern.

Two-spotted lady beetle (Adalia bipunctata) has orange elytra with 1 black spot on each side.

Larval Food


Adult Food

Aphids, thrips, mites, scale insects, and eggs of butterflies and moths.

Ladybug or Lady Beetle?
The term lady beetle is more appropriate than ladybug because the term bug refers to insects in the order Hemiptera and this insect is in the order Coleoptera.

This beetle is to eastern Asia. It was inftoduced into North America to control aphids and scale insects. It is now naturalized.



Coleoptera (beetles)



Polyphaga (water, rove, scarab, longhorn, leaf and snout beetles)









Coccinellidae (ladybird beetles)

  A.K.5000 Harlequin Ladybird

Published on May 24, 2012

Here's another ladybird video on AnimalKingdom5000, this time it's the harlequin ladybird. The harlequin ladybird is originally native to eastern Asia, but was introduced into other parts of the world mainly to control aphid populations. This ladybird was seen in the United Kingdom in 2004. The harlequin ladybird has a dome-shaped body with smooth wing coverings, white markings on its pronotum (typically defining an "M"- or "W"-shaped black area), and usually brown or reddish legs. It occurs in three main colour forms: red or orange with black spots (known as form succinea); black with four red spots (form spectabilis); and black with two red spots (form conspicua). However, numerous intermediate and divergent forms have also been recorded. The number of spots can vary from 0-22 on this species. The harlequin ladybird has the ability to live in diverse habitats. It is most commonly found on deciduous trees, such as Willow, Sycamore and Maple, and on low growing plants such as Nettles. Harlequin Ladybirds feed most commonly on aphids, but have a wide food range, also feeding on scale insects, adelgids, the eggs and larvae of butterflies and moths, many other small insects, including other ladybirds, pollen, nectar, and sugary fluids, including honeydew and the juice from ripe fruits. The harlequin ladybird is very widespread in the United Kingdom has the potential to wipe out some of the native ladybird species in the country.

  Harlequin Ladybirds Harmonia axyridis forms succinea (female) and spectabilis (male) pairing

Published on Jun 1, 2013

The Harlequin or Multivariegate Ladybird Harmonia axyridis, a rather attractive (but potentially very damaging) alien ladybird species, has now been recorded at numerous sites throughout much of the UK. These beetles are Asian in origin and they have been artificially introduced to the USA and several European countries as a form of biological pest control. It would appear that the consequences of earlier artificial introductions of alien species have either never been learned, poorly researched, or otherwise rashly dismissed by those responsible. In the case of the Harlequin Ladybird there are doubtless sophisticated naturally occurring population control factors (e.g. predators, parasites, fungal, bacterial or viral diseases, prey species population cycles) which would keep the numbers in check in their own habitat. However, these same factors are not (yet) operational in the UK. It is highly likely that the parents of the first UK-bred generations arrived by emigration from the northern coast of Belgium - although the arrival of some beetles in produce cannot be ruled out. The Harlequin adults and pupae are both very variable and two of the recognised colour forms (a typical 19-spot 'succinea' female and a four-spotted 'spectabilis' male) have been illustrated here. The white spots on the sides of the pronotum are very obvious in all variant adults and the larvae and pre-pupae are very easy to separate from all of the native British species as they have distinctive orange markings. Several stages of the life-history may be observed at the same time and this species may be capable of producing at least three broods during a single season if conditions are favourable. This insect is predatory on the same prey items (aphids, etc.) as most of the native British ladybird species, but unfortunately also on those useful insects which naturally control garden and crop pests themselves, namely lacewings, hoverfly larvae and other ladybirds, particularly the Two-spot Adalia bipunctata judging from the subsequent population crash of this formerly abundant insect. Now that Harlequin Ladybirds have become numerous the natural balance between these native predator and prey species could be irreparably damaged.
