Leucauge decorata, the decorative silver orb spider, is one of the long-jawed orb weaver spiders. A medium to large sized orb weaving spider, with a body length up to 12 mm long (female). Male to 6 mm. This species has a "point" to the end of the abdomen. Found in Africa, India, south east Asia, also to Australia.

Male. Upperside: violaceous blue, with brilliant iridescent tints in certain lights. Forewing: the costa, apex and termen bordered with black, this edging narrows from base to the middle of the costa, then broadens greatly at apex, where it occupies the apical fourth of the wing, and is again narrowed below vein 4, whence it is continued as an even band to the tornus; on the disc beyond the apex of the cell the ground colour is sensibly paler, and the dark markings of the cell are faintly visible by transparency from below. Hindwing: the costa very broadly, the termen much more narrowly black; the black bordering on the latter consists of a series of rounded coalescent spots, which on the inner side are margined by faint dark lunules; these are formed not by actual scaling but by the dark markings of the underside which show through more or less clearly.Underside: slightly bluish white; the markings, some black, some dusky, but all large and distinct. Forewing: a short bar on the discocellulars, an anteriorly inwardly curved, transverse, discal series of seven, more or less elongate spots, of which the spot in interspace 2 is vertical and sinuous, the next above it irregularly oval and obliquely placed, the next smaller and almost round, the fourth placed almost longitudinally, forms a short bar, and the apical three decrease in size to the costa; beyond these is an inner subterminal, transverse, lunular line, an outer subterminal series of transverse spots and a very slender anteciliary line. Hindwing: two basal and three subbasal spots in vertical order; a line on the discocellulars; a spot above it at base of interspace 6; a much larger spot above that in interspace 7; a lower discal irregular transverse series of five spots, followed by terminal markings similar to those on the forewing, except that the spots in the subterminal row are rounded, not transverse. Cilia of both forewings and hindwings white alternated with dusky black at the apices of the veins. Antennae, head, thorax and abdomen dusky black, the antennae ringed with white; beneath: the palpi, thorax and abdomen white. Female: upperside: white, the bases of the wings and in some specimens the hindwing posteriorly shot with iridescent blue. Forewing: costa, apex and termen broadly black; the discocellulars marked with a very short, fine black line that extends down from the black on the costal margin. Hindwing: costa and apex broadly black; termen below vein 6 with a regular subterminal series of black spots in the interspaces, enclosed within an inner lunular and an outer straight slender anteciliary black line; the veins, except vein 5 in the middle, slenderly black. Cilia of both forewings and hindwings white. Underside: ground colour and markings similar to those of the male. Antennae, head, thorax and abdomen as in the male.In the male there is a small patch of white on the upperside of the forewing beyond the cell and on the upperside of the hindwing on the anterior portion of the disc; the extent of this patch varies on the forewing from a mere touch of white just beyond the cell to a large discal area of white which is diffuse with ill-defined margins. In the female the blue iridescence at the base of the wings on the upperside is in some specimens considerably restricted, in others entirely absent. On the underside in both sexes the ground colour is paler and in form and position the markings are much less prominent, though entirely like those of the wet-season brood.

Distinctive in its solitary lifestyle, black potter wasp has some fascinating behaviors. It notably shapes clay nests in the form of elegant pots—a feat of nature's engineering in the insect world. Within these nests, it lays eggs and stocks caterpillars as food for its offspring. Its role in the ecosystem is vital, regulating caterpillar populations, thus contributing to maintaining the balance of the local ecological dynamics.

The wingspan is about 60–96 mm. Palpi with third joint long and spatulate at extremity. Forewings with crenulate cilia in both sexes. Male has greenish-grey head and thorax. Abdomen orange. Forewings greenish grey with very numerous faint striated reddish lines. There are three rufous spots which can be seen at end of cell. A dark oblique line from near apex to centre of inner margin. A silvery patch found on vein 1 and another below lower angle of cell. A marginal black band with crenulate inner edge. There is a series of white cilia spots. Ventral side is orange. Forewings with costa and apical area blotched with rufous. Oblique postmedial and sub-apical black bands can be seen. Hindwings with apical area blotched with rufous. A black spot found on costa and another beyond lower angle of cell. A marginal black band runs from vein 5 to anal angle. Female much more prominently striated with rufous coloured forewings. The silvery patches found below and beyond cell very large and conjoined crossed by white streaks above vein 2 and beyond cell.

It is a medium-sized dragonfly with brown capped eyes, greenish brown thorax and bluish abdomen. Female lacks the powder blue pruinescence. It prefers medium to slow-flowing streams in the dry zones and hot plains. Adults are common around open rocky and sandy beds of the streams.

Sexes show dimorphism with variable colour morphs. The wingspan of the female is about 46–54 mm, whereas the male's is about 30–40 mm. The adult male has two morphs. The common form is smoke brown with uniformly brown forewings and pale greyish hindwings. In the forewing, black specks and a pale patch outside the subbasal line can be seen. The adult female also has two forms with an areole on each forewing and they lack the white colored portions on forewings which is found on male. The common form has an irregular longitudinal dark brown zone in the center of forewing. The more rare form has pale colours. The underside of the wings are similar in both sexes with less pronounced markings. The full-grown caterpillar is 38–44 mm long. It is hairy with four white or brown dorsal tussocks. It is greyish brown with a crimson-reddish head, legs and prolegs. Head with red stripes found on full-grown caterpillar. Pupation occurs inside a silk cocoon spun between the leaves of the food plant.

The species is on the IUCN Red List as not endangered, year of assessment 2009. The slender bank dragonfly occurs from Southeastern Europe and North Africa to Japan and Australia

The gypsy moth (Lymantria dispar) spends nearly its entire life on the same host tree, stripping leaves off of it. However, they will occasionally fly as a colony from one host tree to another. They are commonly recognized by their fuzzy larvae, which have dark bodies with red and blue spots. The adults are usually a pale brown color though.

Upperside of both sexes brown of varying depths of colour. Forewing: cell with one pair of subbasal and one pair of apical transverse sinuous fasciae, the outermost defining the discocellulars; a short, broad, dark, oblique fascia beyond to vein 4, its inner margin diffuse, its outer sinuous but sharply defined; below vein 4 a sinuous, transverse, more faint fascia, followed by a discal blackish fascia, very broad and diffuse, below costa, bordered by a row of faint ocelli, and a postdiscal and a subterminal similar fascia following the outline of the termen. Hindwing with a slender blackish loop near apex of cellular area; a broad inwardly diffuse, outwardly well-defined short discal fascia in continuation of the one on the forewing; a series of postdiscal somewhat ochraceous ocelli with black pupils minutely centred with white; postdiscal and subterminal broad lines as on the forewing. Underside brown, with very broad darker brown transverse fasciae, the interspaces between the markings irrorated (sprinkled) with purplish silvery scales. Forewing with two sinuous fasciae on basal half succeeded by a discal fascia, very broad at the costal margin and decreasing in width to the dorsum, bearing on its outer border a row of obscure ocelli. This is succeeded by a zigzag dark line, and sinuous subterminal and terminal lines; apex and tornal area suffused with purplish silvery. Hindwing: two irregular, very broad, dark brown, curved short fasciae near base; a straight, transverse, prominent, narrow ochreous-brown discal band defined outwardly by a black line; a transverse postdiscal dark brown fascia, widest in the middle and bearing outwardly a curved row of ochreous-brown white-centred ocelli, followed by a zigzag dark line in continuation of the one on the forewing; a subterminal somewhat diffuse dark fascia and a terminal dark line. Antennae, head, thorax and abdomen dark brown.

D. chrysippus is a medium-sized butterfly with a wingspan of about 7–8 cm (2.8–3.1 in). The body is black with many white spots. The wings are orange, the upperside brighter and richer than the underside. The apical half of the forewing is black with a white band. The hindwing has three black spots in the center. The wings are bordered in black and outlined with semicircular white spots. This species exhibits slight sexual dimorphism, as the Male has large scent glands on his hindwings, which the female lacks. They appear as a large black spot with a white centre if viewed from the underside D. chrysippus is a polymorphic species, so the exact coloring and patterning vary within and between populations. It is similar in appearance to the Indian fritillary (Argynnis hyperbius), which may coexist with it.
