	Psyche 36:283-292
		The arrangement seemed to be perfect that the older nymphs were at that end of the root lower in the soil and towards the ant nest-the younger nearer to the surface of the ground and farther from the nest.
		Most of the nymphs found were thus situated, under the ground, but two chambers were found in a cavity in the rotten stump at about the surface of the ground but covered with trash of dead leaves etc., and in the dirt and debris of very rotton wood.
		Not a single nymph of about 30 was out of the company of ants, and one found under a bit of rotton log about 3' away as well as one found through on the other side of the stump had ants in attendance.

		Nymphs were represented as young, beautiful, musical, amorous, and gentle, although some were associated with the wilder aspects of nature and were akin to satyrs; others were vengeful and capable of destruction, as in the story of Daphne.
		Other important nymphs were naiads, nymphs of streams, rivers, and lakes; nereids, daughters of Nereus, who lived in the depths of the Mediterranean Sea; dryads, tree nymphs; and oceanids, 3,000 ocean nymphs who were the daughters of Oceanus.

	Floriculture: Fact Sheets: Pest Management: Biological Control for Silverleaf Whitefly on Poinsettias
		To distinguish this new, damaging form of SPWF, from the pre-existing, less damaging strain, the old strain was referred to as strain A, and the new strain damaging poinsettia, field crops, and vegetables, was called strain B. By 1987-88, strain B had spread to almost every poinsettia growing region in the United States.
		Work on the biology, morphology, and genetics of strains A and B revealed sufficient difference that strain B was described as a new species of whitefly.
		Should whitefly nymphs begin to increase to a level that is unacceptable, a biorational insecticide that is compatible with parasitoids should be used (e.g., Table 6).

	Augsburg College Biology - Photo of Month - July - August 2002
		Nymphs of both generally spend most of their time sitting still or walking about (often seeking both prey and refuge on underwater vegetation), but both also have means of rapid escape when faced with danger.
		In the case of damselflies, the nymphs can swim by thrashing their bodies back and forth, using their gills to propel them similar to how fish use their tails.
		Whereas some damselflies and dragonflies live near ponds or lakes (which are the bodies of water where the nymphs of those species live), the fl-winged damselflies pictured here are usually found around streams since their nymphs are stream dwellers.

	Augsburg College Biology - Photo of Month - September 2002
		This particular nymph belongs to the family Calopterigidae, a family that was the subject of a recent Photo of the Month story (see the Black-winged Damselfly story for more information and for photos of what this nymph will grow into).
		This undoubtedly provides the nymph some degree of camoflauge, but I don't know whether or not these ciliates are harmful to the nymph (I suspect these ciliates are harmless).
		Like other arthropods, this damselfly nymph has an exoskeleton that is shed (molted) periodically as it grows.

		They are present as half-grown nymphs when the first of their generation emerge.

	Mayfly Species Hexagenia limbata (Hex) Hatch
		The nocturnal nymphs only come out of their burrows to molt, which they do over 30 times in the 2-3 years they take to mature.
		The nymphs are confirmed as a year-round trout food by stomach samples gathered by both the Leonards and Swisher and Richards.
		Fred Arbona writes in Mayflies, the Angler, and the Trout that fishing a nymph deep and lifting it up toward the surface occasionally is the most effective way to fish this hatch.

		Her egg laying and subsequent hatching of nymph mantids are interesting facets of behavior which warrant further investigation.
		Nymphs undergo six to seven molts before adulthood, when the old skin is shed off, to be replaced by larger skin.
		Mantid nymph appetites are voracious, and they immediately begin feeding, often on each other, as soon as they drop from the ootheca.

	Mayfly Family Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Hatch
		Nymphs of this family are a gift to the angler, because many have the peculiar habit of swimming up and down between the surface and the bottom several times before actually emerging.
		Several authors, including, write that some of the nymphs crawl to the high tips of rocks and other objects prior to emergence, where they may be picked off their perches by peckish trout.

		After hatching, the nymphs drop from the twigs to the ground, enter the soil and begin feeding on sap from the roots.
		A nymph will remain underground at a depth of 2 to 18 inches until it is ready for its last molt.
		This occasional tower-building habit of the nymph appears to be influenced by shallow soil, the proximity of the nymph to the surface, conditions of unusual warmth which brings the nymph prematurely to the soil surface, or excessive soil moisture.

	Dirty Secrets of Bloodthirsty Ticks
		He and other experts in tick biology have found that the seemingly primitive parasites use an array of sophisticated chemical strategies to subvert a host's immune defenses, to prevent blood from clotting, and to muffle any itch or pain that might elicit scratching that could dislodge a tick and ruin a vital blood meal.
		For deer ticks, the nymph stage -- the stage milling around in Dr. Wikel's jar -- is the main transmitter of disease to people, with its peak of activity coming from late spring to late summer.
		A nymph's day generally starts in a moist, protected place, typically buried in leaf litter and only rarely out in the middle of a mowed lawn.

		With the exception of the Coquillettidia which have an unusual biology, all larvae are mobile and breath at the water's surface, either directly (Anopheles), or through a siphon (Ochlerotatuss, Culex, Culiseta, Orthopodomyia, Uranotaenia) at the end of the abdomen.
		The nymph does not feed, it draws on the reserves that were built up in the larval stage.
		Nymphs generally stay at the surface of the water but when disturbed, they dive by quickly furling and unfurling their abdomen which has two swimming paddles at the end.

	Developmental biology Summary
		Modern developmental biology studies the genetic control of cell growth, differentiation and "morphogenesis," which is the process that gives rise to tissues, organs and anatomy.
		Embryology and developmental biology today deal with the various steps necessary for the correct and complete formation of the body of a living organism.
		The related field of evolutionary developmental biology was formed largely in the 1990s and is a synthesis of findings from molecular developmental biology and evolutionary biology which considers the diversity of organismal form in an evolutionary context.

		Others are not quite so obvious because the nymphs, (which is the correct word to describe a juvenile hemimetabolous insect) spend all their time in the water, i.e.
		In these cases the nymphs do not look quite as similar to the adult forms as do the wholly terrestrial (living on dry land) insects.
		This is far more obvious with the nymphs of hemimetabolous insects like Stick-insects who often leave their old skins hanging around for people to see.

	GRASSHOPPER BIOLOGY
		Xanthippus corallipes is known to pass the first winter in the egg stage and a second winter as a nymph.
		Nymphs hatching from eggs deposited by swarming adults demonstrated greater gregarious tendencies and more often formed bands compared to nymphs of the same species developing from eggs deposited by non-swarming adults.
		Weather directly affects survival of young nymphs; first-instar grasshoppers are easily killed by heavy rainfall (Criddle, 1933a).

		The gills of the damselflies are in the form of three leaflike structures at the end of the abdomen; in dragonflies the gas exchange occurs internally as water is drawn into the abdomen.
		When the time is right, the aquatic nymph emerges from the water (depending on the species, trees, rocks, mud, any sort of vegetation, etc, might be used).
