Top 20 Most Common Insects in Imatra

With a wingspan of 2.5 - 3 cm, it is very similar in appearance to the small skipper Thymelicus sylvestris. They can be told apart by the undersides of the tips of their antennae: the essex skipper's antennae are black, whereas those of the small skipper are orange.

The brown-spotted mother of pearl butterflies (Boloria selene), also known as swamp-meadow nuthatch butterfly, is a butterfly (butterflies) of the genus Boloria in the family Nymphalidae. The specific epithet is derived from Selene, the moon goddess from Greek mythology. In 2013 he was named butterfly of the year by the BUND environmental foundation.

Male above red-golden, with a narrow black margin, at the proximal side of which there are dark dots on the hindwing: female cinnabar-red, spotted with black, the hindwing partly dusted with black. Underside leather-yellow, more sparsely spotted with black, before the outer third of the hind- wing pale dots, which are occasionally united in a white chain. The anal area dusted with red. The species occurs from the Atlantic coasts throughout Europe to East- Siberia and from the coast of the North Sea to the Mediterranean, but is absent from Great Britain and Japan. — In Lapland flies a small form, oranula Frr. (76 b), which is otherwise very similar to the name-typical form. — estonica Huene (76 b), from the Baltic provinces and eastern Russia, exactly resembles the preceding in size and shape, but has a broader black margin. — virgaureola Stgr. (76 b) is in size like virgaureae, but the upperside of the male is as in estonica; beneath the more reddish disc of the forewing contrasts with the more yellow hindwing and the white discal stripe of the latter is absent or reduced; from northern Central Asia, Dauria, Mongolia, and as similar aberration in the Swiss Alps. — males from the Apennines, in which the upperside is deeper red-golden and the base of the hindwing more densely dusted with dark, are apennina Calb. The females the contrary have the ground-colour paler and are less dusted with dark than many Central European specimens, the underside being hghter. According to Fallou the males from the Pyrenees are also deeper red. - On the other hand, the specimens from Mersina and the neighbouring Taurus Mts. have a bright light golden-red upperside in both sexes, the black margin being narrowed in the male. This is aureomicans Heyne. — Specimens with the underside of the hindwing strongly dusted with grey, the upperside of the female more-over having a brown-grey tint on account of the dark dusting on the golden ground, occur in many alpine districts with the ordinary form, being especially plentiful and well marked in the Alps of Valais; all such individuals are united as ab. zermattensis Fall. (76 a). It is hardly possible to decide from Fallou's very long description of this form which are the real characteristics of his aberration, so that strictly speaking not all the specimens standing in collections under this name belong here, particularly not all the specimens from the Valais; in fact only those individuals are true ab. zermattensis which, like phlaeas caeruleopunctata, have a chain of white dots before the outer third of the hindwing, as shown in the figure given in Ann. Soc. Ent. Fr. vol. V. pl. 2. Besides the modification of the colour of the upperside into sepia-brown, both sexes differ on the underside in the forewing bearing a broad dark margin and the hindwing being washed with fuscous, ab. seriata Fruhst. are zermattensis females which have a discal row of white dots on the hindwing proximally to the row of black spots, ab. fredegunda Fruhst. bears, besides those dots, a row of submarginal spots on the forewing beneath. [more vars described]The egg is semiglobular, grey-green, with a network of polygons, laid singly or several together on the stalk of the foot-plant. Larva green with a yellow stripe on back and at the sides, brownish head and brownish legs; at first glassy, transparent, later yellow on the back. Emerges in April and feeds until June on Rumex and Solidago. Pupa rounded, smooth, similar to a small bean, brownish, with dark markings; on the thorax a dark dorsal longitudinal stripe, which is continued on the abdomen by a row of impressed dots. The butterflies are on the wing from the end of June into August on meadows, clearings in woods, mountain-sides and flowery slopes; they are abundant almost everywhere in the area aru:! ascend in the high mountains above 10,000 ft.

Ochlodes sylvanus has a wingspan of 28–32 mm, which is similar in size to Chequered skipper. Although called "large" this is still a relatively small butterfly and not much larger than either the small or Essex skippers. The body is rather squat. The antennae are hooked at their tips. The upperside of the wings is orange-brown with a brown border and some lighter spots. The underside of the hindwings is greenish-yellow, marked with sparse yellow spots. The male has a broad scented androconial dark line across the top of the forewings. On the hindwings of the females there are brighter square marks. When the wings are opened, the forewings are obliquely folded, masking the hindwings. The faint chequered pattern on both the upperside and underside, and also the hook-shaped antenna tips, help to distinguish the large skipper from these two orange skippers. The Lulworth skipper also has patterned wings, but does not have the hooked antennae. The caterpillar can reach a length of 28 millimetres (1.1 in). It has a large blackish-brown head and a bluish green body, with a dark line down its back and a yellow stripe along each side.

Interestingly, individuals belonging to orange tip (Anthocharis cardamines) occupy different habitats depending on gender: the males inhabit the edges of forests, whereas the females prefer meadows. When laying eggs, females release pheromones to deter other females from laying eggs on the same flowerhead. They are picky about choosing their host plants, and females will avoid plants not fully exposed to sunlight.

Lasiommata maera has a wingspan of 44–56 millimetres (1.7–2.2 in). These large butterflies are quite variable in color and pattern. Usually the upperside is orange in the forewings and mostly brown in the hindwings. The forewings always show a single ocellus, while the hindwings bear two or three ocelli. The underside of the forewings is orange and the underside of the hindwings is marbled with gray brown. This species is quite similar to Lasiommata megera, that is smaller and has paler yellow-orange forewings. Seitz P. maera L. (= adrasta Dup.) (45 d). On an average larger than hiera, more evenly coloured, the black markings of the ground less prominent in the nymotypical form with a sooty brown disc; the forewing of the male more pointed, with longer costal margin and more oblique distal margin; on the underside of the forewing the distal band extends without interruption across the median veins to the hindmargin. The underside of the hindwing has a much purer ground-colour, i. e. there are less clouds and shadows between the various dentate lines which cross the disc. The apical ocellus has a stronger tendency towardsduplication being usually somewhat distorted obliquely and — at least beneath — bearing two pupils. Between this ocellus and the apex there is nearly always a minute eye-dot, there occurring also often specimens with other accessory ocelli . Moreover, the ocelli of the hindwing are as a rule somewhat larger than in the same sex of hiera — A very large material proves that it is hardly possible to find definite trenchant distinctions , especially if one takes into account the large number of local forms of maera, all the various kinds of pattern and coloration exhibiting a great variability.

Brenthis ino is a medium-sized butterfly with a wingspan of 3.5 - 4.5 cm. Females are larger and usually darker than males. The antennae are clavate (club shaped). The basic color of the upper side of the wings is orange with several dark brown blotches. The edges are brown too, with a discontinuous stripe of small blotches. The lower side of the wings is creamy orange with an indented edge and dark brown blotches on the forewings, while the hindwings show brown-edged beige blotches and some ringed dark brown and violet shading spots. The wings of this species lacks any silver blotches.

With a wingspan of 29 to 35 mm (1.1 to 1.4 in), Amanda's blue is noticeably larger than most of the "blue" butterflies, which is particularly apparent when they are flying. The upperside of the male's wings is a silvery blue or sky blue, often, but not always, with a broad dark border and a narrow black marginal line with an outermost white line. The upperside of the female's wings is in some populations dark blue edged with brown but in other populations is medium brown with a row of orange half-moon shaped lunules near the edges. The hind margin has red blotches. The underside of the male's wings are light grey with white-edged black blotches. The underside of the female's wings is similar but they are a rich creamy-brown colour with red blotches, especially on the margins of the hindwings and a series of black spots with white rims, often touching, forming a row parallel to the margin of the wings. The basal areas of the underwings are turquoise. The wingspan is 28 to 36 mm (1.1 to 1.4 in).

The upperside forewings are a bright orange with a dark outside edge border and with eight or nine black spots. The hindwings are dark with an orange border. Some females also have a row of blue spots inside the orange border and are known as form caeruleopunctata. The undersides are patterned in a similar way but are paler. The black spots on the forewings are outlined in yellow and the dark colouring is replaced by a pale brownish grey. The hindwings are the same brown/grey colour with small black dots and a narrow orange border. The caterpillars (larvae) are usually green, but some have a purple stripe down the middle of the back and along each side.

The butterfly has white wings with grey or yellow markings near the center or tip of the wing.
