Mystery of galls on leaves

Post about a mind-blowing observation I made 2day: while coming from office I saw strange nodules on a plant leaves. Out of curiosity I plucked one leaf with nodules n brought home. My guess was it must bel disease which is causing abnormal growth. To check what these nodules made up of, I cut open…

Compound eye of Chironomidae

Midges (Chironomidae) are the most wide spread and numerous insects resembling mosquitoes.  Adult Midges are commonly observed flying in swarms or “clouds”, or are seen resting on fences, walls, under eaves and in protected areas such as porches and entryways.  https://napamosquito.org/vectors-and-pests/mosquitoes/harmless-mosquito-like-insects/

Quick observation

I could get this nice view watching fluids inside this insect. Any ideas what is that? Let me know in the comments below.

Filiform Antenna through Foldscope

The antennae of insect are often called ‘feelers’ because the insect waves them around. This is the wrong name because they are not only used for touch. The antennae are actually the insects ‘nose’ – they are used for the sense of smell. The paired antennae are made up of a number of individual joints….

The Unfolding of Cell Biology

Cells were first discovered by Robert Hook in 1665, who described the building blocks of life as little rooms in which monks lived. Robert Hook witnessed dead plant cells present in cork; it took many years and numerous studies to describe the internal structures of the cell and define Cell Theory. Cell Theory states all…

The exotic insect

At the very beginning, I thought this is Lice but later it turned out to be a completely different one. This time I achieved the best visual clarity so far by implementing new illumination method -See (B) in part 3- Enjoy the observation!

Molted exoskeleton of an insect

I’ve been noticing these odd, insect-like things on my softboard for quite a long time now. I hadn’t been brave enough to touch them, but since they hadn’t moved in forever, I decided to take a closer look. While I mounted it on my slide with forceps, I realized that it was flimsy, and seemed…

Insect and its LUNGS

This post is fr8m a slide which I made months ago. The isect in this slide is arouf 0.25 mm . It is transparent and its lungs are clearly visible . I am not sure if thats really its lungs or not . Si please commemt on your opinion. This post shows the hunger of…

Compound Eye of a Moth

Moths (like many other adult insects) have compound eyes and simple eyes. The Compound eyes are made up of many hexagonal lens/corneas which focus light from each part of the insects field of view onto a rhabdome (the equivalent of our retina). They have simple eyes (ocelli) which can only differentiate dark from light.

Proboscis of a Moth.

Moths have very long proboscis, or tongues, which they use to suck nectar or other fluids. These proboscis are very tightly coiled when not in use, like a hosepipe. When in use, the proboscis are uncoiled to their full length and in some species, that length is remarkably long.

Head part of Mosquito Larvae

The head of the mosquito larva is basically prognathous. The mouthparts, therefore, are considered as anterior appendages. The mandibles and maxillae exhibit a wealth of taxonomic characters that, unfortunately, are not extensively used in mosquito taxonomy. A lateral palatal brush (mouth[/no-lexcion] brush) is borne anteriorly on either side of the mouth. In most larvae, the brushes consist…

Polytene Chromosome from salivary glands of Chironomus Larvae

Polytene chromosomes are giant chromosomes common to many dipteran (two-winged) flies. They begin as normal chromosomes, but through repeated rounds of DNA replication without any cell division (called endoreplication), they become large, banded chromosomes.  Polytene chromosomes are usually found in the larvae, where it is believed these many-replicated chromosomes allow for much faster larval growth than if the cells remained…

Spider

The eye arrangement can be a key factor when identifying spiders to family, and sometimes to genus, but are almost never useful in identifying to species. For identifying to species, spinnerets and leg details (especially first and 4th legs) are also useful. However, the best thing anyone can do is to get an extreme closeup…

Unidentified insect in my balcony

I saw this super small insect this morning, and trapped using a tap. It was a slow moving, so very easy to catch. I tried to picture it but it appears to be some common insect, not able to identify further. Need help in it identification.

Antennae of male mosquito

Mosquitoes use their antennae as movement receivers that respond to oscillations of air particles within the insects’ surroundings. The brush-like male antennae are sensitive to sound waves, particularly to those of the frequency of the wingbeat of females; so when a male midge ‘hears’ a female with his antennae, he flies towards the source of…

Posterior Spiracle of Maggots ( Musca domestica Larvae)

Here’s a beautiful and detailed picture of the processed Posterior Spiracle of the Musca domestica Larvae, which was collected from an infected wound. The larvae was boiled in 10% NaOH for about 5 mins and was thoroughly rinsed in water. It was then dehydrated for 2 – 5 mins in increasing concentrations of alcohol ( 70%,…

Tiny white cohabitants in the worm bin

The springtail is a small and naturally abundant invertebrate with complex mouthparts used to suck fluids from decomposed foods and fungi. What makes them unique is a forked tail-like appendage called a furcula under the abdomen that launches the springtail into the air for a quick getaway. One thing they have in common with red wigglers is that…

Head part of an Ant

Ant heads, especially the eyes and mandibles, come in all shapes and sizes. Ants use their heads to sense information about the world around them. This is very important for their survival and the life of the colony. If you watch an ant’s head, the antennae are always moving back and forth, touching, tasting, and…
