Geographic Range:
Nearctic, Palearctic, Oriental, Ethiopian, Neotropical, Australian, Oceanic Island
Geographic Range description:
Cosmopolitan distribution, including species endemic to New Zealand, Hawaii and many other Pacific islands). Greatest diversity in the tropics. From Scoble, 1992: The Lipeninae are Afrotropical. Poritiinae are Oriental. Liphyrinae are mainly African with a few species in the Oriental and Australasian regions. Miletinae occur mostly in Africa or the Orient, some are present in the Holarctic region. Curetinae are Oriental with a few Palaearctic representatives. Theclinae are represented in all the main zoogeographical areas. Lycaeninae occur mainly in the Holarctic region. Polyommatinae are represented in all major biogeographical areas.
All Blues, Coppers, and Hairstreaks live for a year or less. Many complete their whole life in a few months.

This group of butterflies get their common names from their wings. Some groups have shiny blue on their wings, others are the color of copper. Some have very thin little "tails" on their wings that are called hairstreaks. Many are not so colorful, and have gray or brown wings with spots of black, white, or orange. They are usually small butterflies, with wingspans of 25 mm or less. Some species have males with reduced front legs like the Brushfoot family, but females always have all 6 legs for walking and standing.
Caterpillars in this family have small heads and legs, and sometimes look like slugs covered with tiny hairs. Most are green or brown, but a few are yellowish or reddish. Some can pull in their heads completely, like a slug.
Other Physical Features: ectothermic ; bilateral symmetry
Sexual Dimorphism: female larger; male more colorful

After mating, females lay eggs one by one on the flowers, twigs or leaves of food plants. This group often has two generations a year, one that spends the winter as caterpillars or pupae and fly as adults in the spring, and a second that complete their life-cycle in the summer and fly as adults in the fall.
Breeding season: May to October in Michigan.
Key Reproductive Features: iteroparous ; seasonal breeding ; sexual ; oviparous
These butterflies don't care for their young.
Parental Investment: no parental involvement

Texture:
ridged
Description of egg morphology:
From Scoble, 1992: "The diameter of the egg usually exceeds that of its height, or the egg may be almost spherical. Often, lycaenid eggs are pitted or bear projections. In eggs of most species parts of the highly porous chorion is perforated by numerous pores enable it to act as a plastron when eggs are submerged in rain water (Downey and Allyn, 1981)"
Pupa life history description:
Some Lycaenidae produce sound by abdominal stridulation: rows of tubercles on the posterior edge of segment A5 are rubbed against rows of tubercles on the anterior edge of segment A6.
Larval abdomen description:
From Scoble 1992: "The larva (Downey in Stehr, 1987) is usually onisciform, resembling the shape of a woodlouse." "The abdomen often bears a dorsal gland on segment A7, a pair of eversible organs on segment A8, and minute, round "pore cupolas' associated particularly with the dorsal gland and the eversible organs."
Abdominal glands:
absent
Crochets:
uniserial
Crochet arrangement description:
From Scoble 1992: Crochets are usually "tri- to multiordinal, and arranged in an interrupted mesoseries."
Systematic and taxonomic history:
The relationhip between the lycaenids and riodinids is undetermined. Traditionally the riodinids have been considered a subfamily within the Lycaenidae, but this is not well supported. Harvey (1987) proposed 5 characters (based on early stages) that support a sister relationship between the two groups. However, Robbins (1988a, 1990)
Pupa description:
From Scoble, 1992: "The pupal is often girdled. Where not girdled, it may be positioned at an angle to the substrate or be suspended with the head downwards."
