Synchlora pectinaria
Synchlora pectinaria is a species of emerald moth in the family Geometridae, described by Grossbeck in 1910. Like other members of the genus Synchlora, its caterpillars are known for adorning their bodies with bits of plant material—flower petals, leaves, and other vegetation—to achieve remarkable camouflage. This behavior, shared with the more widespread S. aerata, makes the larvae exceptionally difficult to detect among the flowers and foliage they consume. The species is part of the emerald moth group (subfamily Geometrinae), characterized by their typically green adult coloration.
Synchlora xysteraria
Singed Emerald
Synchlora xysteraria is a small geometrid moth in the emerald moth genus Synchlora. First described by George Duryea Hulst in 1886, this species has a restricted distribution limited to the southeastern United States (Georgia and Florida) and the Caribbean islands of Cuba and Hispaniola. Like other members of its genus, larvae are known for their remarkable camouflage behavior, adorning their bodies with plant material from their host plants. The species is one of approximately 12 Synchlora species found in North America.
Tetragnatha
Stretch Spiders, Long-jawed Orb Weavers
Tetragnatha is a large genus of long-jawed orb-weaving spiders with hundreds of species distributed worldwide, though most occur in tropical and subtropical regions. These spiders are characterized by their elongated bodies, extremely long legs, and notably elongated chelicerae (jaws) with well-developed teeth. They construct horizontal orb webs, often near water, and many species can run across water surfaces. The genus exhibits remarkable variation in dispersal ability, with some species being excellent dispersers capable of colonizing islands, while others appear to have secondarily lost this capacity. Hawaiian Tetragnatha species have undergone adaptive radiation, with some lineages evolving cursorial (running) behavior and abandoning web-building entirely.

Tetragnatha dearmata is a species of long-jawed orb weaver spider in the family Tetragnathidae. The species was described by Thorell in 1873 and has a transcontinental distribution spanning North America and Eurasia. Like other members of the genus Tetragnatha, it possesses characteristically elongated chelicerae and a slender body form adapted for camouflage in vegetation. Specific details of its biology and ecology remain poorly documented in the available literature.
Tetragnatha extensa
Common Stretch Spider
Tetragnatha extensa is a long-jawed orb-weaver spider with a Holarctic distribution. It is characterized by an extremely elongated body and legs, with females reaching up to 11 mm in body length. The species constructs horizontal orb webs in damp, vegetated habitats and exhibits a distinctive straight-line defensive posture when alarmed. It is the most common species of Tetragnatha in the United Kingdom and among the most frequently encountered long-jawed orb weavers across its range.
Tetragnathidae
Long-jawed Orb Weavers, Long-jawed Orbweavers
Long-jawed orb weavers are a family of spiders characterized by elongated bodies, long legs, and often extraordinarily long chelicerae (jaws). Most species construct orb webs in a horizontal or near-horizontal plane, distinguishing them from the vertical webs typical of Araneidae. The family includes diverse ecological specialists: meadow-dwelling species that camouflage as grass stems, riparian species that build webs over water, and cave-dwelling species adapted to dimly lit environments. Some species exhibit social behavior, forming communal webs spanning extensive areas.
Thesprotia
Grass-like mantids
Thesprotia is a genus of small, cryptic praying mantids in the family Thespidae. Species in this genus are known for their grass-like appearance and exceptional camouflage among vegetation. The genus contains 14 Neotropical species, with most distributed in South America and one species, Thesprotia graminis, occurring in the southeastern United States. These mantids are considered beneficial due to their predatory habits.
Tibellus
Slender Crab Spiders
Tibellus is a genus of active-hunting spiders in the family Philodromidae, commonly called slender crab spiders. They are characterized by elongated, flattened bodies with longitudinal dorsal stripes that provide camouflage on grasses and vegetation. Unlike web-building spiders, they pursue prey directly on low vegetation. The genus contains 51 recognized species distributed across Eurasia, Africa, the Americas, and Australia. Adults range from 4–15 mm in body length.
Tibellus maritimus
Maritime Running Crab Spider
Tibellus maritimus is a species of running crab spider in the family Philodromidae, characterized by its slender body and vertical striped pattern that provides effective camouflage on grasses and foliage. The species is notable within its genus for lacking the two dark dorsal spots on the abdomen that distinguish related species such as T. oblongus and T. asiaticus. It is the only Tibellus species in the Canadian portion of its range without these spots. The spider hunts by ambush, lying flattened on vegetation to capture prey.
Tibellus oblongus
oblong running spider, slender crab spider
Tibellus oblongus is a Holarctic spider in the family Philodromidae. It is an active hunter that does not construct webs, instead pursuing and ambushing small insect prey. The species exhibits distinctive elongated body morphology with longitudinal striping that provides camouflage in grassy vegetation. Adult females measure 6–11 mm in body length, with males slightly smaller at 5–8 mm. Females construct flattened egg sacs and guard them until spiderlings emerge.
Timema cristinae
Cristina's Timema
Timema cristinae is a small, flightless stick insect endemic to a restricted region of southern California chaparral. The species exhibits striking color-pattern polymorphism with green, striped, and melanic morphs that provide differential camouflage on two host plants: Adenostoma fasciculatum (chamise) and Ceanothus spinosus. It has become a prominent model system for studying ecological speciation, host adaptation, and the interplay between natural selection and gene flow. The species reproduces sexually with females laying single eggs coated in ingested soil, which require soil contact for successful development.
Tracheini
Tracheini is a tribe of leaf-mining jewel beetles (Coleoptera: Buprestidae) in the subfamily Agrilinae. The tribe comprises primarily two genera: Habroloma and Trachys. These beetles are characterized by their small size and specialized larval habit of mining leaves of woody and herbaceous plants. Adults are typically found on host plant foliage. The tribe has a cosmopolitan distribution with notable diversity in Japan (32 species recorded) and South America. Two new Japanese species, Habroloma elaeocarpusi and H. taxillusi, were described in 2023, expanding known host associations to include Elaeocarpaceae and Loranthaceae.
Trogulidae
Trogulid Harvestmen
Trogulidae is a family of harvestmen (order Opiliones) comprising approximately 65 extant species across five genera: Anarthrotarsus, Anelasmocephalus, Calathocratus, Kofiniotis, and Trogulus. Members are characterized by short legs, flattened leathery bodies, and a distinctive habit of adhering soil particles to their bodies for camouflage. The family is primarily distributed in western and southern Europe, extending to western North Africa, the Levant, the Caucasus, and northern Iran. One species, Trogulus tricarinatus, has been introduced to eastern North America. The family includes the only Trogulidae species in Ireland, Anelasmocephalus cambridgei, which has a specialized life history involving egg-laying in empty snail shells.
