In Hong Kong, this species is only recorded from mangrove habitats, or on the odd "good night" dispersing individuals might be recorded in other habitats up to 10km from mangrove.

Class:Insecta
Order:Lepidoptera
Family:Lycaenidae
Genus:Celastrina
Species:C. argiolus
Binomial name
Celastrina argiolus
Habitat: Locally found where remnants of woodland contain Holly. It is sometimes found in urban gardens and parks with suitable habitats.
It is double brooded from Dublin southwards and single brooded in the north.
Larval Food Plant: Holly Ilex aquifolium
Ivy Hedera helix
Flight Time: April and May
Mid-July to September (second generation)
Hibernation: Overwinters as a pupa.
In both sexes the ground colour of the upper wings of the adult is silvery-blue and tinged with lilac.
In the male upperwings there is a narrow black band on the margins of the forewings, wider at the apex and becoming thinner at the tornus. Chequered margins at termination of veins on forewings. The black marginal band is absent on the hindwings.
The female upperwings are darker than in the males and have a more pronounced and wider marginal band on the forewing. Each hindwing has a series of 6 submarginal black spots. Chequered margins at termination of veins on the forewings.
The underside in both sexes is similar the ground colour being a bluish-white with black spots.
Life Cycle of the Holly Blue
Ovum:
The white disc shaped egg is laid singly at the base of unopened flower buds on Holly in the spring brood and on Ivy in the summer brood.
Eggs hatch after 10-16 days, depending on the season.
Larva:
This fairly stout larva measures up to 16 mm in length, tapering towards the extremities.
The larva has a few recognised colour forms but usually when fully grown it is a translucent pale green sometimes with purplish-pink dorsal and lateral stripes. It has a shiny black retractile head.
On the dorsal surface of the 10th segment there is a honey gland (Newcomer's gland) whose secretions are attractive to ants. The body is covered with short whitish setae.
The larva emerges in May and feeds until early July inside the developing drupes on the female Holly tree and on the young terminal leaves of the male Holly tree.
The second brood larva feeds on the developing buds or flowers of Ivy during late August and September.
Prior to pupation the larva becomes a dull purplish colour and wanders from its food plant to pupate.
This larval stage lasts c.26 days.
See Holly Blue parasite - Listrodromus nycthemerus below.
Pupa:
Pupation probably takes place secreted by twigs and bark among the tangled roots and dead leaves within the growth of Ivy or on the undersurface of a Holly leaf. The pupa is attached by cremasteral hooks to a silk pad and supported by a silken girdle.
Pupa from the spring generation hatch within 10-18 days. Those from the summer generation overwinter , spending about 6 months in the pupal state.
Adult:
The adult emerges and is on the wing from mid-April to June and again in mid-July to September where it may be seen flying around holly bushes above head height.
Holy Blue Parasite:
The host specific parasitic Ichneumon wasp, Listrodromus nycthemerus, targets the Holly Blue butterfly by laying its egg in the larvae.
Here the Listrodromus grub lives and feeds on the body tissue of the developing butterfly larva.
Eventually the life cycle of this parasitoid, which is approx. 11mm in length, is completed inside the host and results in the emergence of a single adult Listrodromus wasp from what appears to be a normally formed Holly Blue pupa. The pupa dies soon after the emergence of the wasp.
The wasp will then seek new generation Holly Blue larvae in which to inject its egg.
There is evidence that the wasp population gradually builds up over a number of years and eventually, when it gets plentiful, kills a large proportion of pupae resulting in a 'crash' in Holly Blue numbers.
This produces a shortage of food for the parasitoid and its numbers also crash allowing the Holly Blue butterfly population return to normal.
The length of the Holly Blue-Ichneumon wasp cycles observed in Britain - from boom to bust - is about seven years.

65-70mm (2.37 inches)
This rather large migrant is mainly dark brown with bright red stripes.
The underside has colourful patterns.
It is attracted to gardens where it feeds on buddlea, several other flowering species and also over-ripe fruit.

La détermination des membres de la famille des Tetrigidae m'apparaît trop difficile pour que j'ose nommer une espèce même avec un (?) accolé.
J'ai l'espoir qu'un spécialiste (je pense notamment bien sûr à Josip Skejo) aura le temps et des éléments photographiés suffisants pour étiqueter cette espèce.

Family: Nymphalidae
Genus: Pararge
Species: P. aegeria
Binomial name
Pararge aegeria
Habitat: The Speckled Wood is widespread and common in Ireland seen typically along woodland clearing, hedgerows and fields.
This species is double brooded and possibly treble brooded
Larval Food Plant: Numerous grasses such as -
False Broom Brachypodium sylvaticum
Yorkshire-fog Holcus Ianatus
Flight Time:
Two to three overlapping broods which may be seen from
April to October
Hibernation: May overwinter in larval or pupal states
This species is territorial and patrols a beat. The male has a band of androconial scales on its forewing.
Life Cycle of the Speckled Wood
Ovum:
The glossy pale yellow eggs are c.0.8 mm high and flattened at the base. They are laid singly on the blades of
a wide range of grasses in April or May and again in the summer. Hatching occurs between 8-23 days,
depending on the temperature.
Larva: On emerging, the larvae do not always eat the eggshell but remain close to it on the leaf.
They feed inwards from the margins of the leaf to the midrib.
The first brood larvae feed by day and night and are fully grown in 25-30 days when they enter pupation.
The larvae of the late summer brood are unusual in that they either hibernate as larvae or pupate before
hibernating and therefore can be found overwintering in either state.
It has been found that when the autumn is cool, larvae emerging from eggs as early as mid-August remain
in the larval stage and overwinter in this state. While in warmer temperatures larvae emerging as late as
the end of September develop rapidly enough to pupate in November and overwinter in this state. These
pupae hatch the following spring producing butterflies as early as March but more usually in April and
May. While the overwintering larvae do not produce larvae until later in spring. This larval stage lasting
at least 7 months.
Pupa: The duration of the pupal stage is variable and dependant on temperature and time of year. In summer it may
be as short as 10 days, but in the overwintering pupal stage it can last roughly from November to April.
The pupa is attached by cremasteral spines to a silken pad spun on the underside of leaves of the foodplant
or adjacent vegetation. The cast larval skin is always attached to the pupa.
Adult:
Adults can emerge continuously from April to mid-October. There tends to be an overlap among different
generations and in warm summers there may be three broods with old worn specimens still on the wing
in October.
Both sexes feed on the honeydew of ash, oak and birch or nectar from ragwort. Mating and ovipositing
take place from April onwards.
The outer margins of the females wings are more rounded and the creamy-yellow patches usually larger
than the males althought there is a marked seasonal variation in bothe sexes.
The oblique band of blackish androconial scales in the centre of the male forewings are difficult to see.
