The antennal lobe is a sphere-shaped deutocerebral neuropil in the brain that receives input from the olfactory sensory neurons in the antennae and mouthparts. Functionally, it shares some similarities with the olfactory bulb in vertebrates.
Which insect has a lobed antenna?
Metamorphosis of the Insect Nervous System The metamorphosis of the antennal lobes has been most extensively studied in Lepidoptera such as Manduca sexta (Hildebrand, 1985). The receptor axons from the adult antenna project to an association area in the deutocerebrum, the antennal lobes.
What does the green gland do in crustaceans?
Paired maxillary and antennal glands (also called green glands) are the principal excretory organs in crustaceans. The “labyrinth” of the antennal gland is also involved in reabsorption of glucose, amino acids, and divalent ions from tubule fluids.
Do all insects have exoskeletons?
An exoskeleton, in contrast to an endoskeleton, is an external anatomical feature that supports and protects an animal’s body. All arthropods (such as insects, spiders and crustaceans) and many other invertebrate animals (such as shelled mollusks) have exoskeletons.
Which animals have antennas?
All flies have antennae. Members of the suborder Nematocera (e.g., crane flies, various midges, and gnats) have whiplike antennae with two basal segments (scape and pedicel) and a flagellum of many similar segments.
Which antenna is present in Butterfly?
Antennae (singular antenna) are sensory appendages attached to the head of butterflies and moths. Antennae are used for the sense of smell and balance. Butterflies have two segmented antennae with a small club at the end of each. Moths have antennae without the club.
What does the antennal gland do?
They function as osmoregulatory organs. For example, in the antennal gland of the freshwater crayfish (Astacus), fluid is filtered from the blood into an end sac and passes through a tubular labyrinth, where ions are reabsorbed, to produce a hypotonic urine that passes via a renal tubule to the bladder.
What is the function of the green glands antennal glands in the crayfish?
antennal gland (green gland) Either of a pair of ducts (coelomoducts) found in the third segment of a crustacean and opening to the exterior at the base of the second antenna. They function as osmoregulatory organs.
What is the excretory organ in crustaceans like prawns?
The main excretory organs of prawn are paired green glands. They are located within the second antennae which are the second pair of appendages, attached to the anterior part of the body. Each green gland consists of on endsac, labyrinth and a bladder.
How do insects move with an exoskeleton?
In insects, however, muscles are directly attached to their exoskeletons. Because the exoskeleton is not a single surface but consists of multiple jointed plates, the insect’s muscle movement causes the connected exoskeleton plate to move as well. This muscle/plate movement allows insects to move around.
Which organism has an exoskeleton?
Insects, spiders and shellfish are some of the invertebrates that have exoskeletons. The exoskeleton provides them with strength and support, as well as protecting the organs inside their bodies. To grow, animals with exoskeletons need to shed their old skeleton and grow a new one.
Which insect has an exoskeleton?
Insects are the largest group of animals that have an exoskeleton. Insects have exoskeletons made of a substance called chitin. The exoskeletons of crabs, lobsters, shrimp, spiders, ticks, mites, scorpions, and related animals are also made of chitin.
What animal has 3 hearts?
Octopuses Octopuses have blue blood, three hearts and a doughnut-shaped brain. But these aren’t even the most unusual things about them!
Does a June bug have antenna?
Like other scarab beetles, June bugs are oval-shaped, with six stout legs and fat antennae. They are generally between 1/2 and 1 inch long, and may be brown, black or maroon, without any discernible patterns.
What is an insect antenna?
The antennae are a pair of sense organs located near the front of an insect’s head capsule. … They are usually covered with olfactory receptors that can detect odor molecules in the air (the sense of smell). Many insects also use their antennae as humidity sensors, to detect changes in the concentration of water vapor.
Can butterflies live without antenna?
Instead of just using their eyes to distinguish day from night, butterflies use their antennae as light receptors. … When butterflies lose their antennae, they aren’t able to determine time as well as those with intact antennae, butterfly researcher Dr. Steven Reppert told BBC News.
Do all insects fly?
The ability to fly is not determined by the number or size of wings. Some insects with large wings, such as Dobsonflies and Antlions, are relatively poor fliers, while bees and wasps with smaller wings are good fliers.
What do butterflies drink?
nectar Butterflies use their proboscis to drink sweet nectar from flowers. Nectar sometimes resides deep within a flower and the proboscis allows the butterfly to reach this sugary treat.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
