This document summarizes information about Odonata, an order of insects that includes dragonflies and damselflies. It describes their key physical characteristics like large multifaceted eyes. It outlines the major families, differences between dragonflies and damselflies, their life cycles from egg to adult, predatory behavior as nymphs and adults, mating processes, economic importance as natural mosquito predators, and some interesting facts.
Orthoptera is an order of insects that comprises the grasshoppers, locusts and crickets, including closely related insects such as the katydids and wetas. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts and close relatives; and Ensifera – crickets and close relatives.

Thrips (order Thysanoptera) are minute (mostly 1 mm long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. A SEMINAR ON ODONATA
M.S.SWAMINATHAN SCHOOL OF AGRICULTURE
Centurion University of Technology & Management,
Paralakhemundi ,Odisha
Presented By- Sunandan Swain
Tapan Kumar Behera
Debasish Das
2. CHARCTERS:-
• Rectangular stigma
• Large compound eyes
• Short, bristle like antennae
• They have reduced antennae since their use is limited.
• Eyes, are well developed: they are huge and multifaceted, thus providing
excellent eyesight.
• Odonates are experts at detecting movement and colour (including UV and
polarised light).
3. MAJOR FAMILIES:-
Damselflies (Zygoptera)
• close their wings along the abdomen when at rest.
• Their four wings have similar shape.
• Damselflies are slender insects and tend to be weak flyers.
• Their big eyes are clearly separated and located either side of their head (a
bit like hammerhead sharks.
• front and hind wings are stalked (narrow at the base) and similar in size and
shape.
Dragonflies (Anisoptera)
• keep their wings open when at rest.
• Their front and hind wings have different shapes.
• Their eyes are so huge they often touch the top of their head.
• hind wings have enlarged anal region (broader toward the base than front
wings).
5. LIFE CYCLE:-
• Life cycle – Odonates only have three life stages: egg-larva-adult (as opposed to
butterflies, for instance, there is no pupa stage here).
• Eggs hatch within a few weeks into dull, brownish larvae, which can live underwater
for several months to several years depending on species.
• During “emergence”, larvae climb out of the water onto a leaf or twig.
• Their skin splits at the back of their head and thorax, allowing the young adult to
emerge, unfold its wings and its abdomen.
• Young adults will mature over several days away from water.
• They head back to rivers and ponds/lakes at maturity. Adult males often keep a
territory and will be on the lookout for females. Mating is often brief.
• Females will either lay their eggs directly into the water, or insert individual eggs
inside the leaves and stems of emergent or floating vegetation.
6. FEEDING:-
• Odonate nymphs are predaceous .
• Use their modified labium or mask to capture insect.( crustacean , molluscan
or oligochaete)
• They have tactile or vibrational cues that helps them to identify the insect
• which are burrowed in their substrate.
• It is a special order in which in immature stages they have well developed
eyes for hunting.
• Adult have large compound eye to detect insect prey ,they grasp with their
legs while flying .
7. MATING OF ODONATA:-
• Males place sperm packet on second abdominal
segment
• Males have claspers on the end of the abdomen
• They clasp a female behind the head
• Fly “in tandem” while the female bends the
abdomen forward to pick up the sperm
• Males may clasp on to another male to complete
for access to female
8. ECONOMIC IMPORTANCE:-
• They feed on small flying insects such as mosquitoes.
• They may also catch and eat honey bees , so regarded as pests by the beekeepers.
• In some parts of Europe, dragonflies are considered a threat to the poultry industry because
they transmit Prosthogonimus pellucidus, a parasitic flatworm. Dragonfly naiads become
infected by ingesting cysts of the flatworm. These cysts survive into adulthood of the dragonfly
and may spread to birds (particularly poultry) that catch and eat the adult dragonflies. The
flatworm cysts dissolve in the bird’s intestine and infection spreads into the cloaca and
reproductive organs. The Dutch have a maxim: “Hide the hens, the dragonflies are coming.”
9. FUN FACTS :-
• The compound eyes of some dragonflies may have up to 28,000 facets.
• Some naiads can shoot out their labium and catch prey in only 25 milliseconds.
• Scientists have documented large-scale migrations of dragonflies. One swarm was
observed 1,400 km off the coast of Australia.
• Some immature damselflies establish feeding territories, areas that are defended
against invasion by other conspecifics. Territorial species develop more rapidly and
produce larger adults than other non-territorial species.
• Many adult male dragonflies establish and defend territories along the perimeter
of a lake or stream. Females will mate only with males that hold a territory, so
population density is somewhat regulated by territory size.
10. • MaleMost dragonfly naiads can move forward by “jet
propulsion”. Rapid contraction of the rectal muscles forces water out
the rear end and shoots the insect forward.
• Male damselflies (and perhaps some dragonflies) have a special
flagellum associated with the copulatory organ that can reach into a
female’s body and remove sperm deposited by another male in a
previous mating.
• Dragonflies are known by many interesting common names, including
“snake doctors”, “devil’s darning needles”, and “mosquito hawks”.
• Can catch and eat 60 mosquitoes in one minute
