spiracle

franki as well as spinulae patterns and posterior and anterior spiracles.

First metasomal segment: petiolate, with wide part posteriorly = 0; filiform = 1; filiform basally, widening gradually after spiracles = 2; filiform basally, widening abruptly after spiracles = 3; filiform basally, little widened after spiracles = 4 20.

I examined the spiracles on 12 species of Phlaeothripidae recorded in California at desert localities or on desert plants.

Unlike of other species of Cynipidae (Viggiani & Nugnes 2010), in the different larval instars of this species were not observed mandibular asymmetry nor variation in number and position of the spiracles.

Abdominal spiracles I 0.56 mm long and 0.41 mm wide, shorter than spiracles II-VIII.

There are 10 pairs of spiracles (2 thoracic and 8 abdominal, see Fig.

1C), 1.10-1.50 mm long and 0.44-0.62 mm wide (N = 4); length through spiracles 1.79-1.83 mm (N = 2); 10 pairs of spiracles, the second pair larger (10 [micro]m) than others (5 pm; N = 4 measured specimens).

Marginal hyperemia of the pectoral and pelvic fins; increased beating of the spiracle; variation in motor activity with hyperexcitation phase; and contraction in the gill region, for expulsion of water through the spiracles.

"These scary looking insects communicate by pushing air through openings in their abdomen, called 'spiracles'.This loud hissing noise helps to startle predators and give the cockroach time to escape.The hissing cockroach's flattened body allows it to squeeze through tight spaces in search of food and to escape predators.

The posterior spiracles were located deep inside a fossa, surrounded by more than 10 tubercles (Figure 1(b)).

It will clog their spiracles (through which they breathe) and kill them.

On both sites between the segments A3-A4, areas surrounding the spiracles are white.

These holes are known as spiracles. This squeezing action causes a shrill sound that can last for several seconds, and appears to have the ability to scare away predators.
