2. PrefaceThere are places on Earth where over thousand birds stage during migration and where birders and experts flock to cherish this grand congregation, one of such places is Long Point. Situated in Lake Erie, Long Point Sand spit was created over the last 4,000 years due to the high shoreline availability of glacial till, strong winds, variations in climate, hydrological cycle and seiches. These forces continue to shape Long Point, the largest sandy peninsula (or Sand spit) on the Great Lakes.Long Points Inner and Outer Bays and their associated marshes are one of the most biologically important areas not only for resident birds but for migratory waterfowls of North America as well. This is because Long Point falls under the Atlantic flyway of migrating birds, providing them stopovers for feeding. One can easily guess why thousands of birds decide to stop at Long Point Bay it is diverse in its floral and faunal diversity from various aquatic plants and animals to diverse insects on land this land is as rich in providing fuel for the migratory birds as it is to feed the resident song-birds. Long Point is well known for its waterfowls, but this often leads to ignorance in the minds of the nature enthusiasts who come to cherish the biodiversity at Long Point. Besides Waterfowls and song-birds, some mammals such as Grey Fox and Badgers are on top of the food pyramid but what we easily miss out here is what supports this wildlife the lesser-known creatures such as snakes, arachnids and insects.This is a photo-documentation of the fauna of Long Point and the surrounding areas, consisting of Port Rowan and Turkey Point, which I observed over the two months. 3. AcknowledgmentLong Point Waterfowl (LPW) has given me the opportunity to work as well as learn about the Great Lakes ecology. I am thankful to LPW staff for encouraging me to explore and for the guidance. I would like to thank Scott Petrie and Ted Barney for entrusting me with the work I love doing. I would like to thank Robin Churchill, without whom I would not know so much about freshwater invertebrates as I do today. Casey Peet-Pare and Laura Robson, for teaching me how to track snakes, and manage the species-at-risk species such as Hog-nose snakes, and to my colleagues and friends for their support and guidance.Last but not the least; I would like to thank Holly Sanderson, for selecting me for the Masters in Environment & Sustainability degree, and to my classmates who made me feel at home. 4. Insecta 5. Insecta is the most diverse Class of Kingdom Animalia. They are easily recognized by the presence of six legs and a hard exoskeleton. It may sound surprising, but insects are the one that run the planet. They not only form a nutritious base of a food-web, but are also help maintain our gardens and forests by providing ecological services such as pollination and decomposition.Insects are omnipresent, and the first ones to stumble upon, whether you are home or in your garden, are ants. These so common, yet not-so-well-known bugs are as important to an ecosystem as the plants. Surprisingly, we do not know enough about ants to merely ignore them. This fact is backed by new research and discoveries carried out every year. At Long Point, I managed to photograph and study a few species of ants, along with other bugs such as bees, wasps, beetles, butterflies and dragonflies. This section is a little effort to appreciate the beauty of lesser known critters we share our homes with.Other than plants, they form the base of a large food-web at Long Point for song birds or waterfowls, and the ecosystem of Long Point and surrounding area would not exist without insects. Hence their abundance is appreciable by watching birds stage at Long Point during migration who consume insects and other invertebrates along with plants. 6. Ants, Bees and Wasps of Long Point Formica ant Formica sp. Formica ants are one of the most abundant ants at Long Point. Known for their big mounds of nests made up using plant materials such as pine-needles, they are also capable of nesting high above the ground. 7. False Honey antCarpenter ant Prenolepis sp. Camponotus sp. False Honey Ants are the first ants to be seen as soon as Spring Carpenter ants, notorious for their habit of burrowing in furniture arrives, hence they are also known as Winter Ants. The and causing economic damage, are actually beneficial in a natural photographed ant is a female who has shed her wings and is now ecosystem. In their natural environment, they nest in fallen wooden looking for a site to establish a new nest.logs, thereby hastening the decomposition rate and enriching thesoils. 8. Green Metallic Bee These solitary, iridescent bees are commonly seen collecting pollen. Observations worldwide have shown a decline in bee populations, without whom the plants cannot pollinate, and fail to reproduce. This failure will not only impact an ecosystem but our basic food supply as well. 9. Leaf-cutting/ Resin Bee Megachile sp. True to their name, this is one of the largest genera of bees. They build nests underground or in natural cavities. Like any other bee, they are beneficial for pollination. Interestingly, I have observed these bees undergo daily torpor in flowers. 10. Spider Wasp Spider Wasps are specialized for hunting spiders. Like many wasp species, they primarily feed on nectar, but hunt to provide food for the larva. A Spider Wasp will maneuver itself such that it stings the spider under its abdomen. The paralyzed spider is then carried into a nest cavity and the wasp lays an egg on it. The paralyzed spider is kept from decaying - fresh food for the emerging larvae. 11. Tiger Beetles of Long Point Cicindela formosa Tiger Beetles are the fastest beetles in the world. True to their name, they either ambush or stalk their prey just as a Tiger would. C. formosa is a large, common beetle seen on inland dunes and coasts of the Great Lakes. It is the largest Tiger Beetle of Canada. Other species of Tiger Beetles seen at Long Point are displayed on the next page. 12. Cicindela lepidaCicindela punctulata Cicindela scutellaris Cicindela sexguttata 13. Ladybird Beetles of Long PointSeven-spot LadybirdCocinella septempunctataLadybird beetles are efficient pest controllers of aphids and scale insects. For this reason, many species of Labybird beetles were introduced toNorth America, such as Seven-spot Ladybird, Multicoloured Asian Ladybird beetle and Russian wheat-aphid Lady beetle photographed below. Irecorded five species, out of which only two Spotted Ladybeetle and Glacial Ladybeetle are native to Canada. 14. Spotted LadybeetleGlacial Ladybeetle Multicoloured Asian Ladybird beetle Russian wheat-aphid Ladybird beetle 15. Other Beetles of Long Point Flower Longhorn Beetle Analeptura lineola Belonging to the Order Coleoptera, beetles have the largest number of known species. Many new species are discovered every year. The beetles of Long Point are abundant in numbers as well as in diversity. Some other commonly occurring beetles of Long Point are displayed on the next page. 16. Click Beetle Stag Beetle Milkweed Longhorn BeetleLonghorn Beetle Green Immigrant Leaf Weevil 17. Flies of Long Point Robber Fly Flies are amongst least appreciated insects in the world. It is because of their association with dead and decaying matter, and the fact that some spread diseases such as mosquitoes and other biting flies. Yet there are beneficial flies such as Robber flies, who actively feed on mosquitoes thereby acting as biological pest controllers, and there are flies such as Hover flies, which assist in pollination. Some other common flies are displayed on the next page. 18. Picture-winged Fly Hover fly Crane fly Robber flyTachinid fly Bee-mimicking Robber fly 19. Butterflies of Long Point Juvenals Duskywing Erynnis juvenalis Butterflies are one of the most intricately evolved insects. There are various shapes, sizes and colours of butterflies, from a dull-looking Duskywing, which prefer to be well camouflaged on the ground, to Swallowtails, which flaunt their brilliant colours warning predators of their toxicity. These organisms, famed for their metamorphosis, are as beautiful and diverse as the birds at Long Point are. There are thirteen species I could document. 20.

Mourning Cloak Nymphalis antiopa 30. Monarch Danaus plexippus Male 31. Bronze Copper Lycaena hyllus Male 32. Eastern Tiger Swallowtail Papilio glaucus Male 33. Dragonflies of Long Point Calcio Pennant Celithemis elisa Dragonflies are one of the oldest living organisms. They were present in the times when dinosaurs roamed the planet. Most of their lifetime is spent as aquatic nymphs, where they are voracious predators of fish as well as mosquito larva. On land, the adults are specialized in aerodynamics, feeding on anything they can hold onto. The dragonfly diversity at Long Point is astounding, thanks to the extensive freshwater habitats. 34.

Damselflies of Long PointSedge SpriteNehalennia ireneDamselflies are cousins of Dragonflies. Although the life-stages on-land and under-water are alike, they considerably differ from Dragonflies.Long Point serves as an ideal habitat for damselflies as well. Well-known for their bright colours, they ar
