The pale coloration provides camouflage for the beetle on the light sand. [7] The larvae are grub-like, with long, segmented bodies and large jaws similar to those of adults. [6] Habroscelimorpha dorsalis dorsalis, commonly known as the Northeastern beach tiger beetle, is the largest subspecies of Habroscelimorpha dorsalis. [8]
The northeastern beach tiger beetle is one of the physically larger subspecies of Cicindela dorsalis with a body length if roughly 12–17 millimetres (0.47–0.67 in). Its hardened forewings, also called elytra, acquire varying shades of white and tan. The northeastern beach tiger beetle has wings hidden under these elytra.
The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator. [6] The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates.
Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. [1] [2]For protection against ticks and mosquito bites, the U.S. Centers for Disease Control (CDC) recommends DEET, icaridin (picaridin, KBR 3023), oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), IR3535 and 2-undecanone with the caveat that higher percentages of the active ingredient ...

In recent years, reports of the use of heavy duty bug sprays as an illicit drug have gained notoriety. [15] Although products such as Raid are relatively safe to humans (when used as intended), the act of huffing, smoking, snorting, vaping, plugging, drinking and/or injecting Raid or other bug sprays can cause irreversible neurological damage ...

[2] [11] [12] Systemic insecticides penetrate into the plant and move (translocate) inside the plant. Translocation may be upward in the xylem, or downward in the phloem or both. Systemicity is a prerequisite for the pesticide to be used as a seed-treatment. Contact insecticides (non-systemic insecticides) remain on the leaf surface and act ...
