Insects That Start With H

When most people think of insects, they tend to imagine bothersome bugs that invade their homes or swarm around outdoor lights. However, there’s much more to these tiny creatures than meets the eye. Insects are a diverse and complex group of animals that have adapted to countless niches and lifestyles. They range from the microscopic to the meter-long, from the solitary to the social, and from the harmless to the deadly. They also exhibit a vast array of astounding behaviors, such as pollination, parasitism, mimicry, bioluminescence, and migration.

Creating a list of insects was a challenging task, but one that I was determined to tackle. I spent countless hours researching and reading about different insect species, and in the end, came up with a comprehensive guide. From creepy crawlies to colorful butterflies, my list has it all.

So, let’s begin exploring this list of insects starting with H!

79 Insects That Start With H

And here’s the list of insects that begin with H letter.

Hackberry Blistergall Psyllid

The Hackberry Blistergall Psyllid, also known as Pachypsylla celtidismamma, is a small insect that causes unsightly galls on hackberry trees. These galls are formed when the female psyllid lays its eggs on the leaves of hackberry trees. As the larvae grow, they secrete chemicals that cause the leaf tissue to swell and form a blister-like growth around the developing psyllids. These galls can be alarming to homeowners, as they may appear to be a serious disease of the tree, but they do not typically harm the tree’s overall health.

Hackberry Engraver

The Hackberry Engraver, also known as the Xylotrechus colonus, is a beetle species that attacks the trunks and branches of hackberry trees. These beetles bore into the wood of the tree, leaving pencil-sized holes in their wake. While the damage caused by these beetles may look severe, it typically does not cause long-term harm to the tree. However, large populations of these beetles may weaken the tree, making it more susceptible to other diseases and pests.

Hackberry Lace Bug

The Hackberry Lace Bug, also known as the Corythucha ciliata, is a small insect that feeds on the leaves of hackberry trees. This bug has lace-like wings and feeds by piercing the leaves of the tree and sucking out the sap. While the damage caused by the Hackberry Lace Bug may not be severe, large populations of these insects can weaken the tree and cause it to become more susceptible to other pests and diseases.

Hackberry Nipplegall Maker

The Hackberry Nipplegall Maker, also known as Pachypsylla celtidismamma, is a type of psyllid that creates small, round growths on the leaves of hackberry trees. These growths, known as nipplegalls, are caused by the feeding activities of the immature psyllids. While these growths may be unsightly, they typically do not cause long-term harm to the tree.

Wrapping Up

And that’s our list of H insects.

I poured my heart and soul into creating a list of insects that was both comprehensive and informative. I read countless articles, consulted with experts, and cross-checked my information to ensure accuracy. The result is a detailed guide that anyone can use as a reference.

Insects are a fascinating creature that dwells in almost every corner of the earth. They have an amazing ability to adapt to their surroundings, and some species can live in the most extreme environments. Some ants, for instance, can survive underwater for almost an hour, while some moths can fly for thousands of kilometers. Insects’ incredible diversity makes them integral to the world’s living systems, performing vital functions that are critical to many species’ survival. Owing to the human-induced environmental changes, insect populations are facing mass extinction. It is high time people took proactive measures to protect their surroundings, preserve insect habitats, and prevent their extinction.

Hope this post on insects beginning with H alphabet has been useful to you!
