The largest members of the family are the 5 cm (2 in)-long bull crickets (Brachytrupes) which excavate burrows a metre or more deep. The tree crickets ( Oecanthinae ) are delicate white or pale green insects with transparent fore wings, while the field crickets ( Gryllinae ) are robust brown or black insects.
In G. gryllotalpa, the burrow is somewhat roughly sculpted; in G. vineae, the burrow is smooth and carefully shaped, with no irregularities larger than 1 mm. In both species, the burrow has two openings at the soil surface; at the other end is a constriction, then a resonating bulb, and then an escape tunnel. A burrow is used for at least a week.
Ticks are parasitic bloodsuckers, capable of spreading deadly disease, and they’re becoming increasingly common. Here’s what you need to know about them.
A habitat preferred by ticks is the interface where a lawn meets the forest, [67] or more generally, the ecotone, which is unmaintained transitional edge habitat between woodlands and open areas.

Unlike ticks from other genera, [8] deer ticks do not have eyes. [3] [8] The scutum is dark, inornate (plain), and, in unfed females, contrasts with the exposed orange or red remainder of the idiosoma. [3] There are no festoons. [3] [9] Ixodes ticks have an anal groove that resembles a horseshoe [9] on their underside anterior to the anal pore.
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs (because they fly to lights in large numbers), alligator ticks, or alligator fleas (in Florida). They are the largest insects in the order Hemiptera. [1]
